Description

紫外線感知キット、紫外線測定方法、および、紫外線感知キット用ユニットUltraviolet Sensing Kit, Ultraviolet Measuring Method, and Unit for Ultraviolet Sensing Kit
　本発明は、紫外線感知部材を用いて紫外線を測定するための、紫外線感知キット、これを用いる紫外線測定方法、および、紫外線感知キット用ユニットに関する。 The present invention relates to an ultraviolet sensing kit, an ultraviolet measuring method using the same, and an ultraviolet sensing kit unit for measuring ultraviolet rays using an ultraviolet sensing member.
　従来より、食品および食器等の殺菌、理美容器具の殺菌、ならびに、医療器具の殺菌などに、紫外線が利用されている。
　また、最近は、新型コロナウイルス感染症（ｃｏｖｉｄ－１９（ｃｏｒｏｎａｖｉｒｕｓ　ｄｉｓｅａｓｅ　２０１９））の流行に伴って、新型コロナウイルスの殺菌に紫外線を利用することが検討されている。 BACKGROUND ART Conventionally, ultraviolet rays have been used for sterilization of foods, tableware, and the like, hairdressing and beauty instruments, and medical instruments.
Recently, along with the epidemic of the novel coronavirus infection (covid-19 (coronavirus disease 2019)), the use of ultraviolet rays for sterilization of the novel coronavirus is being considered.
　紫外線による殺菌を確実に行うためには、対象となる物品等に十分な線量の紫外線を照射する必要がある。すなわち、殺菌を確実に行うためには、所定強度以上の強度の紫外線を、所定時間以上、照射する必要がある。
　しかしながら、紫外線は非可視光線であり、目視によって強度を検知することは、非常に困難である。
　そのため、紫外線量の測定には、通常、紫外線光量計が用いられている。紫外線光量計としては、半導体の光起電力を利用した装置が一般的に知られている。しかしながら、紫外線光量計は、高価であり、また、持ち運びも不便である。 In order to ensure the sterilization by ultraviolet rays, it is necessary to irradiate a sufficient dose of ultraviolet rays to the target articles. That is, in order to perform sterilization reliably, it is necessary to irradiate ultraviolet rays having a predetermined intensity or more for a predetermined time or longer.
However, ultraviolet light is invisible light, and it is very difficult to visually detect its intensity.
Therefore, an ultraviolet photometer is usually used to measure the amount of ultraviolet rays. A device that utilizes the photovoltaic force of a semiconductor is generally known as an ultraviolet light meter. However, the ultraviolet light meter is expensive and inconvenient to carry.
　これに対して、容易に持ち運びができ、様々な場所で簡易に紫外線量を測定できる手段として、紫外線の照射で発色し、かつ、紫外線量に応じて濃度が変化する、紫外線感知シートが知られている。 On the other hand, as a means for easily carrying and measuring the amount of ultraviolet rays in various places, there is known an ultraviolet sensitive sheet that develops color when irradiated with ultraviolet rays and whose density changes according to the amount of ultraviolet rays. ing.
　例えば、特許文献１には、マレイン酸樹脂、セルロース誘導体樹脂、ポリビニルアルコール樹脂、アルコール性水酸基を有するポリエステル樹脂、アルコール性水酸基を有するブチラール樹脂およびアルコール性水酸基を有するアクリル樹脂から選択される少なくとも１種の樹脂を主成分とするインキビヒクルと、ロイコ染料と、を含む紫外線量検知インキ、ならびに、この紫外線量検知インキによる印刷を施した紫外線感知シートが開示されている。 For example, Patent Document 1 describes at least one selected from a maleic acid resin, a cellulose derivative resin, a polyvinyl alcohol resin, a polyester resin having an alcoholic hydroxyl group, a butyral resin having an alcoholic hydroxyl group, and an acrylic resin having an alcoholic hydroxyl group. and a leuco dye, and a UV sensitive sheet printed with this UV dose detecting ink.
　また、特許文献２には、特定波長の光を選択的に透過するフィルタ層と、発光色素および光酸化剤を内包したカプセルを含む紫外線感知層とを有する紫外線感知シートが開示されている。 In addition, Patent Document 2 discloses an ultraviolet sensitive sheet having a filter layer that selectively transmits light of a specific wavelength and an ultraviolet sensitive layer that includes capsules encapsulating a luminescent dye and a photooxidant.
特開平９－１１１１６１号公報JP-A-9-111161 国際公開第２０１６／０１７７０１号WO2016/017701
　このような紫外線感知シートを用いることにより、任意の場所で簡易に紫外線量を測定できる。
　その反面、紫外線感知シートは、感度が不十分な場合もあり、数分の測定時間では、十分に発色しない場合がある。そのため、紫外線感知シートを用いた紫外線量の測定は、時間がかかる場合があるという問題が有る。 By using such an ultraviolet sensitive sheet, the amount of ultraviolet rays can be easily measured at any place.
On the other hand, the sensitivity of the UV-sensitive sheet may be insufficient, and a measurement time of several minutes may not produce sufficient color. Therefore, there is a problem that the measurement of the amount of ultraviolet rays using the ultraviolet sensitive sheet may take a long time.

　その中でも、殺菌能力が波長２５４ｎｍの紫外線と同等で、かつ、人体に反復照射しても皮膚ガン等を発症しない波長２００～２３０ｎｍの紫外線は、測定対象として、より好適に例示される。具体的には、波長２００～２３０ｎｍとしては、例えば、波長２２２ｎｍの紫外線が例示される。
　この点を考慮すると、集光レンズ１６は、波長２２２ｎｍの紫外線の透過率が７０％以上であるのが好ましく、８０％以上であるのがより好ましく、９０％以上であるのがさらに好ましい。
　なお、集光レンズ１６の紫外線透過率は、分光透過率計等を用いて測定することができる。 Here, the ultraviolet rays to be measured are not limited, and examples thereof include ultraviolet rays having wavelengths that are used in various known applications. Among them, UV-C with a wavelength of 100 to 280 nm, such as ultraviolet rays with a wavelength of 254 nm, which have been widely used for sterilization, are suitable examples.
Among them, ultraviolet light with a wavelength of 200 to 230 nm, which has the same sterilizing ability as that of ultraviolet light with a wavelength of 254 nm and does not cause skin cancer or the like even when repeatedly irradiated to the human body, is more preferable as a measurement target. Specifically, as the wavelength of 200 to 230 nm, for example, ultraviolet rays with a wavelength of 222 nm are exemplified.
Considering this point, the condenser lens 16 preferably has a transmittance of 70% or more, more preferably 80% or more, and even more preferably 90% or more for ultraviolet rays having a wavelength of 222 nm.

When the condenser lens 16 is detachably attached to the through hole 16a, a plurality of types of condenser lenses 16 may be exchangeable.
　筐体１４における集光レンズ１６の保持方法、すなわち、貫通孔１６ａへの集光レンズ１６の装着方法には、制限はなく、公知の方法が、各種、利用可能である。

As shown in FIG.
In the ultraviolet sensing kit 10, the ultraviolet sensing sheet 12a is thereby detachably supported by the lower plate 14b of the housing 14. As shown in FIG. That is, as described above, the housing 14 (lower plate 14b) acts as a support section that detachably supports the ultraviolet sensitive sheet 12a.
　紫外線感知キット１０は、集光レンズ１６によって紫外線を紫外線感知シート１２ａに集光することで、紫外線量の測定を行う。従って、集光レンズ１６が集光した紫外線を適正に紫外線感知シート１２ａに照射できるように、下板１４ｂは、紫外線感知チップ１２の位置決め手段を有するのが好ましい。
　紫外線感知チップ１２の位置決め手段には、制限はなく、公知の板状物の位置決め手段が、各種、利用可能である。 The ultraviolet sensing kit 10 measures the amount of ultraviolet rays by condensing the ultraviolet rays onto the ultraviolet sensing sheet 12a with the condensing lens 16. As shown in FIG. Therefore, the lower plate 14b preferably has means for positioning the UV sensing chip 12 so that the UV sensing sheet 12a can be properly irradiated with the UV rays condensed by the condensing lens 16. FIG.
The positioning means for the ultraviolet sensing chip 12 is not limited, and various known plate-like positioning means can be used.
　一例として、図３に概念的に示すように、下板１４ｂに、略Ｌ字型の平面形状を有する当接部材２０を、２個、設け、矩形の紫外線感知チップ１２の２つの角部を当接部材２０に突き当てることで、位置決めを行う方法が例示される。あるいは、このような当接部材２０を、４個、設け、紫外線感知チップ１２を上方から挿入して、４つの角部で位置決めを行う方法も利用可能である。
　別の方法として、図４に概念的に示すように、紫外線感知チップ１２の対向する辺の端部近傍を挿入可能なガイド部材２４と、ガイド部材２４が挿入する辺に隣接する辺に当接する当接部材２６とを用いて、紫外線感知チップ１２の位置決めを行う位置決め手段も利用可能である。この方法においては、当接部材２６は１個でもよく、あるいは、必要に応じて３個以上でもよい。 As an example, as conceptually shown in FIG. 3, two contact members 20 having a substantially L-shaped planar shape are provided on the lower plate 14b, and two corners of the rectangular ultraviolet sensing chip 12 are provided.

Positioning means for positioning the UV sensing chip 12 using the contact member 26 can also be used. In this method, one abutment member 26 may be provided, or three or more may be provided as required.

　このような本発明の紫外線感知キット１０は、図５の断面図に概念的に示すように、紫外線殺菌装置の紫外線ランプ等が照射した測定対象となる紫外線ＵＶを、集光レンズ１６から入射する。集光レンズ１６に入射して集光された紫外線ＵＶを、紫外線感知チップ１２の紫外線感知シート１２ａに照射する。
　紫外線感知キット１０では、このような紫外線の照射を、予め設定された所定時間行うことにより、紫外線感知シート１２ａを発色させ、かつ、その発色濃度で、紫外線ＵＶの線量を測定する。 As conceptually shown in the cross-sectional view of FIG. 5 , the ultraviolet ray sensing kit 10 of the present invention receives ultraviolet rays UV to be measured, which are emitted from an ultraviolet lamp of an ultraviolet sterilization device or the like, from a condenser lens 16 . . The ultraviolet sensing sheet 12 a of the ultraviolet sensing chip 12 is irradiated with the ultraviolet rays UV incident on and condensed by the condenser lens 16 .
In the ultraviolet sensing kit 10, the ultraviolet sensing sheet 12a is colored by irradiating the ultraviolet rays for a predetermined time, and the dose of the ultraviolet rays UV is measured based on the coloring density.
　すなわち、本発明の紫外線感知キット１０は、単に、紫外線感知シート１２ａに測定対象となる紫外線ＵＶを照射するのではなく、集光レンズ１６によって集光した紫外線ＵＶを、紫外線感知シート１２ａに照射する。
　従って、本発明の紫外線感知キット１０（紫外線測定方法および紫外線感知キット用ユニット）によれば、単に紫外線感知シート１２ａに測定対象となる紫外線ＵＶを照射した場合に比して、測定対象となる紫外線ＵＶの紫外線感知シート１２ａへの照射量を、大幅に向上できる。すなわち、本発明の紫外線感知キット１０によれば、見掛け上、紫外線感知シート１２ａの感度を、大幅に向上できる。
　その結果、本発明の紫外線感知キット１０によれば、短時間の測定で、紫外線感知シート１２ａを十分に発色させて、迅速かつ正確に、紫外線量の測定を行うことができる。 That is, the ultraviolet sensing kit 10 of the present invention does not simply irradiate the ultraviolet sensing sheet 12a with the ultraviolet rays UV to be measured, but irradiates the ultraviolet sensing sheet 12a with the ultraviolet rays UV condensed by the condensing lens 16. .
Therefore, according to the ultraviolet sensing kit 10 (ultraviolet measuring method and ultraviolet sensing kit unit) of the present invention, compared to the case where the ultraviolet sensing sheet 12a is simply irradiated with the ultraviolet ray to be measured, the ultraviolet ray to be measured The irradiation amount of UV to the ultraviolet sensitive sheet 12a can be greatly improved. That is, according to the ultraviolet sensing kit 10 of the present invention, the apparent sensitivity of the ultraviolet sensing sheet 12a can be significantly improved.
As a result, according to the ultraviolet sensing kit 10 of the present invention, it is possible to make the ultraviolet sensing sheet 12a sufficiently colored in a short time, and to measure the amount of ultraviolet rays quickly and accurately.
　上述のように、図１および図５等においては、便宜的に、筐体１４の図中上方を上板１４ａ、同下方を下板１４ｂとして、図中上方から紫外線ＵＶを入射している。
　しかしながら、本発明の紫外線感知キット１０は、上板１４ａを上方（鉛直方向の上方）に向けて使用するのに制限はされない。すなわち、紫外線感知キット１０は、下板１４ｂによって紫外線感知チップ１２を適正に支持（保持）できれば、例えば、上板１４ａを横に向けて、横方向（水平方向）から紫外線ＵＶを入射してもよく、あるいは、上板１４ａを下に向けて、鉛直方向の下方から紫外線ＵＶを入射してもよい。
　また、筐体１４の側面に紫外線感知チップを支持して、筐体１４内に光路変更用の鏡を設け、上板１４ａから入射した紫外線を、鏡で反射して光路を変更し、筐体１４の側面に支持した紫外線感知チップ１２の紫外線感知シート１２ａに入射するようにしてもよい。 As described above, in FIGS. 1 and 5, for convenience, the upper side of the housing 14 in the drawing is the upper plate 14a and the lower side thereof is the lower plate 14b, and the ultraviolet rays UV are incident from the upper side in the drawing.
However, the ultraviolet sensing kit 10 of the present invention is not limited to use with the upper plate 14a directed upward (upward in the vertical direction). That is, if the ultraviolet sensing chip 12 can be properly supported (held) by the lower plate 14b, the ultraviolet sensing kit 10 can be used, for example, even if the upper plate 14a is turned sideways and ultraviolet rays UV are incident from the lateral direction (horizontal direction). Alternatively, the upper plate 14a may be directed downward, and the ultraviolet rays UV may be incident from below in the vertical direction.
In addition, the ultraviolet sensing chip is supported on the side surface of the housing 14, a mirror for changing the optical path is provided in the housing 14, and the ultraviolet ray incident from the upper plate 14a is reflected by the mirror to change the optical path, thereby changing the optical path of the housing. The light may be incident on the ultraviolet sensing sheet 12a of the ultraviolet sensing chip 12 supported on the side of 14 .
　紫外線感知キット１０は、集光レンズ１６で集光した紫外線を、紫外線感知チップ１２の紫外線感知シート１２ａに照射することで、紫外線量の測定を行う。従って、効率の良い測定を行うためには、集光レンズ１６によって集光した紫外線が、紫外線感知シート１２ａの全面に照射され、かつ、紫外線感知シート１２ａ以外の領域に照射されないようにするのが好ましい。
　この点を考慮すると、本発明の紫外線感知キット１０においては、集光レンズ１６の焦点距離（レンズパワー）に応じて、集光レンズ１６によって集光した光ができるだけ紫外線感知シート１２ａの全面のみに照射されるように、筐体１４の高さ、すなわち、集光レンズ１６と紫外線感知シート１２ａとの距離を設定するのが好ましい。言い換えれば、本発明の紫外線感知キット１０においては、筐体１４の高さに応じて、集光レンズ１６によって集光した光が、できるだけ紫外線感知シート１２ａの全面のみに照射されるように、集光レンズ１６の焦点距離を選択するのが好ましい。 The ultraviolet sensing kit 10 irradiates the ultraviolet sensing sheet 12a of the ultraviolet sensing chip 12 with the ultraviolet rays condensed by the condensing lens 16, thereby measuring the amount of ultraviolet rays. Therefore, in order to perform efficient measurement, the ultraviolet rays condensed by the condensing lens 16 should be irradiated on the entire surface of the ultraviolet sensitive sheet 12a and should not be irradiated on areas other than the ultraviolet sensitive sheet 12a. preferable.
Considering this point, in the UV sensing kit 10 of the present invention, the light condensed by the condensing lens 16 is directed only to the entire surface of the UV sensing sheet 12a as much as possible according to the focal length (lens power) of the condensing lens 16. It is preferable to set the height of the housing 14, that is, the distance between the condensing lens 16 and the ultraviolet sensitive sheet 12a so as to be irradiated. In other words, in the ultraviolet sensing kit 10 of the present invention, the light collected by the condenser lens 16 is concentrated according to the height of the housing 14 so that only the entire surface of the ultraviolet sensitive sheet 12a is irradiated as much as possible. The focal length of optical lens 16 is preferably selected.
　筐体１４の形成材料には、制限はなく、十分な剛性の筐体を形成できるものであれば、樹脂材料、金属、紙、木材、および、これらの材料を組み合わせた材料等の各種の材料が利用可能である。
　また、筐体１４は、線量の測定対象となる紫外線を透過してもよく、不透過であってもよい。すなわち、筐体１４は、測定対象となる紫外線に対して、透明であっても不透明であってもよい。
　しかしながら、高精度な紫外線量の測定を行うことができる点で、少なくとも筐体１４の上面１４ａは、集光レンズ１６以外の領域が線量の測定対象となる紫外線に対して不透明であるのが好ましい。より好ましくは、筐体１４は、集光レンズ１６以外の部分は、全面的に、線量の測定対象となる紫外線に対して不透明である。なお、線量の測定対象となる紫外線に対して不透明とは、紫外線の透過率が５０％以下であることを示す。 The material for forming the housing 14 is not limited, and various materials such as resin materials, metals, paper, wood, and materials combining these materials can be used as long as they can form a housing with sufficient rigidity. is available.
Further, the housing 14 may be transparent to the ultraviolet rays whose dose is to be measured, or may be impermeable. That is, the housing 14 may be transparent or opaque to the ultraviolet rays to be measured.
However, at least the upper surface 14a of the housing 14, other than the condenser lens 16, is preferably opaque to the ultraviolet rays whose dose is to be measured, in order to be able to measure the amount of ultraviolet rays with high accuracy. . More preferably, the entire portion of the housing 14 other than the condenser lens 16 is opaque to the ultraviolet rays whose dose is to be measured. In addition, opacity with respect to ultraviolet rays to be measured for dose means that the transmittance of ultraviolet rays is 50% or less.
　また、紫外線感知シート１２ａへの紫外線の入射効率の向上、すなわち、上述した紫外線感知シート１２ａの見掛け上の感度を向上するために、筐体１４の内面は、測定対象となる紫外線を反射する反射面であるのが好ましい。なお、反射面とするのは、１面のみでもよいが、複数面が好ましく、面数が多い方がより好ましく、内面全面であるのがさらに好ましい。
　反射面は、測定対象となる紫外線に応じて、公知の各種の物が利用可能である。一例として、アルミニウム等の金属を用いた金属蒸着面等が例示される。 Further, in order to improve the efficiency of incidence of ultraviolet rays on the ultraviolet sensitive sheet 12a, that is, to improve the apparent sensitivity of the ultraviolet sensitive sheet 12a described above, the inner surface of the housing 14 has a reflective surface that reflects the ultraviolet rays to be measured. A surface is preferred. Although only one surface may be used as the reflecting surface, a plurality of surfaces is preferable, a larger number of surfaces is more preferable, and the entire inner surface is more preferable.
Various known reflecting surfaces can be used depending on the ultraviolet rays to be measured. An example is a metal deposition surface using a metal such as aluminum.
　筐体１４の形状は、図示例の立方体状に制限はされず、例えば、正四角柱状、直方体状および六角中状などの角柱状、円柱状、楕円柱状、角錐台状、および、円錐台状等の各種の形状が利用可能である。
　また、筐体１４の形状を、例えば角錐台状等の形状にして、小さい方の底面を測定を行う紫外線感知チップ１２と同じ形状とし、此処を紫外線感知チップ１２の支持面としてもよい。この構成では、上述した紫外線感知チップ１２の位置決め手段を不要にできる。 The shape of the housing 14 is not limited to the cubic shape of the illustrated example, and may be, for example, a prismatic shape such as a square prismatic shape, a rectangular parallelepiped shape, or a hexagonal medium shape, a columnar shape, an elliptical columnar shape, a truncated pyramid shape, or a truncated cone shape. Various shapes such as are available.
Alternatively, the housing 14 may be shaped like a truncated pyramid, with the smaller bottom surface having the same shape as the UV sensing chip 12 to be measured, and used as the support surface for the UV sensing chip 12 . With this configuration, the positioning means for the ultraviolet sensing chip 12 described above can be eliminated.
　なお、このような紫外線感知キット１０の使用形態、筐体１４の高さ、筐体１４の内面、ならびに、筐体１４の形成材料および形状等に関しては、後述する、集光部材として凹面鏡を用いる態様に関しても、同様である。 Regarding the usage pattern of the ultraviolet sensing kit 10, the height of the housing 14, the inner surface of the housing 14, and the material and shape of the housing 14, a concave mirror is used as a light collecting member, which will be described later. This also applies to aspects.
　本発明の紫外線感知キット１０において、紫外線感知チップ１２（紫外線感知シート１２ａ）は、基本的に、使い捨てである。
　従って、１回の紫外線量の測定が終了したら、使用済みの紫外線感知チップ１２と筐体１４から取り出し、次の紫外線量の測定を行うために、未使用の紫外線感知チップ１２を、筐体１４内の下板１４ｂに装着する必要がある。すなわち、紫外線感知キット１０においては、筐体１４内に、紫外線感知チップ１２を出し入れ可能にする必要がある。 In the UV sensing kit 10 of the present invention, the UV sensing chip 12 (UV sensing sheet 12a) is basically disposable.
Therefore, after one measurement of the amount of ultraviolet rays is completed, the used ultraviolet sensing chip 12 and the housing 14 are removed, and the unused ultraviolet sensing chip 12 is placed in the housing 14 for the next measurement of the amount of ultraviolet rays. It must be attached to the inner lower plate 14b. That is, in the ultraviolet sensing kit 10, the ultraviolet sensing chip 12 must be removable from the housing 14. As shown in FIG.
　紫外線感知キット１０において、筐体１４の中に紫外線感知チップ１２を出し入れ可能にする方法には、制限はなく、筐体内に板状物を出し入れ可能にする公知の方法が、各種、利用可能である。
　一例として、筐体１４の上板１４ａ、下板１４ｂ、および、側板のいずれか１枚を、開閉可能な扉とし、この扉から、紫外線感知チップ１２を出し入れする方法が例示される。ここで、図示例においては、上板１４ａは、集光レンズ１６を保持する保持部材として作用する。従って、上板１４ａを開閉可能にするのは、光学的な誤差を招く可能性が有り、好ましくない。
　また、筐体１４の側板のいずれか１面、または、下板１４ｂに、開閉可能な扉を設け、この扉から、紫外線感知チップ１２の出し入れを行う方法も、利用可能である。
　また、筐体１４の側板のいずれか１面に開口を設けて、この開口から、紫外線感知チップ１２の出し入れを行うようにしてもよい。 In the ultraviolet sensing kit 10, there is no limitation on the method of making it possible to insert and remove the ultraviolet sensing chip 12 into and out of the housing 14, and various known methods of making it possible to insert and remove a plate-shaped object into and out of the housing can be used. be.
As an example, one of the upper plate 14a, the lower plate 14b, and the side plate of the housing 14 may be a door that can be opened and closed, and the UV sensor chip 12 can be taken in and out through this door. Here, in the illustrated example, the upper plate 14 a acts as a holding member that holds the condenser lens 16 . Therefore, making the upper plate 14a openable and closable may cause an optical error, which is not preferable.
A method of providing an openable and closable door on one of the side plates of the housing 14 or on the lower plate 14b and inserting and removing the ultraviolet sensing chip 12 through this door can also be used.
Alternatively, an opening may be provided in one of the side plates of the housing 14, and the ultraviolet sensing chip 12 may be inserted and removed through this opening.
　さらに、図６に概念的に示すように、紫外線感知チップ１２を支持（載置）するためのカセットのような支持台２８を設け、かつ、筐体１４の側面に、この支持台２８を挿入するための開口（スロット）を設けてもよい。
　すなわち、本例では、紫外線感知チップ１２を支持する支持台２８を出し入れすることにより、筐体１４への紫外線感知チップ１２の出し入れを行う。 Further, as conceptually shown in FIG. 6, a cassette-like support base 28 is provided for supporting (mounting) the ultraviolet sensing chip 12, and this support base 28 is inserted into the side surface of the housing 14. Apertures (slots) may be provided for this purpose.
That is, in this example, the ultraviolet sensing chip 12 is inserted into and removed from the housing 14 by inserting and removing the support base 28 that supports the ultraviolet sensing chip 12 .
　図１等に示す紫外線感知キット１０は、紫外線感知チップ１２（紫外線感知シート１２ａ）を収容する筐体１４を有するものであるが、本発明は、これに制限はされない。
　例えば、図７に概念的に示す紫外線感知キット３０のように、集光レンズ１６の保持部材である天板３４、および、天板３４を支持する脚部３２を有する枠体３６と、枠体３６が載置される面の、集光レンズ１６による紫外線の集光部に配置された紫外線感知チップ１２とで、本発明の紫外線感知キットを構成してもよい。
　また、図１等に示す筐体１４から下板１４ｂを除き、同様に、この下板１４ｂを有さない筐体と、この筐体が載置される面の、集光レンズ１６による紫外線の集光部に配置された紫外線感知チップ１２とで、本発明の紫外線感知キットを構成してもよい。
　これらの構成では、紫外線感知キットは、紫外線感知チップ１２（紫外線感知シート１２ａ）を着脱自在に支持する支持部を有さない。 Although the ultraviolet sensing kit 10 shown in FIG. 1 and the like has a housing 14 that houses the ultraviolet sensing chip 12 (ultraviolet sensing sheet 12a), the present invention is not limited to this.
For example, like the ultraviolet sensing kit 30 conceptually shown in FIG. An ultraviolet sensing kit of the present invention may be configured with the ultraviolet sensing chip 12 placed in the ultraviolet condensing portion by the condensing lens 16 on the surface on which the 36 is placed.
In addition, except for the lower plate 14b from the housing 14 shown in FIG. An ultraviolet sensing kit of the present invention may be configured together with the ultraviolet sensing chip 12 arranged in the light condensing section.
In these configurations, the ultraviolet sensing kit does not have a support for detachably supporting the ultraviolet sensing chip 12 (ultraviolet sensing sheet 12a).
　あるいは、図７に示す紫外線感知キット３０において、脚部３２の下端に、図１に示す筐体１４の下板１４ｂのような板材を設け、この板材を、紫外線感知チップ１２の支持部としてもよい。この支持部には、上述した紫外線感知チップ１２の位置決め手段を設けるのが好ましい。 Alternatively, in the ultraviolet sensing kit 30 shown in FIG. 7, a plate member such as the lower plate 14b of the housing 14 shown in FIG. good. Preferably, the support is provided with positioning means for the ultraviolet sensing chip 12 described above.
　さらに、図７に示す紫外線感知キット３０において、天板３４に変えて、図８に概念的に示すような、外枠３８ｂと梁３８ｃとによって、集光レンズ１６を保持する保持部３８ａを支持する保持枠３８を用いてもよい。
　あるいは、図１等に示される筐体１４において、上板１４ａに変えて、図８に示す保持枠３８を用いてもよい。 Further, in the ultraviolet sensing kit 30 shown in FIG. 7, instead of the top plate 34, a holding portion 38a holding the condenser lens 16 is supported by an outer frame 38b and beams 38c as conceptually shown in FIG. You may use the holding frame 38 which carries out.
Alternatively, a holding frame 38 shown in FIG. 8 may be used instead of the upper plate 14a in the housing 14 shown in FIG. 1 and the like.
　上述した例は、集光部材として集光レンズ１６を用いた例であるが、本発明の紫外線感知キット（紫外線感知キット用ユニット）は、これに制限はされない。
　例えば、本発明の紫外線感知キットは、集光部材として、凹面鏡を用いてもよい。
　図９に、その一例を概念的に示す。 The above example is an example using the condensing lens 16 as the condensing member, but the ultraviolet sensing kit (unit for the ultraviolet sensing kit) of the present invention is not limited to this.
For example, the ultraviolet sensing kit of the present invention may use a concave mirror as the condensing member.
FIG. 9 conceptually shows an example thereof.
　図９に示す紫外線感知キット４０は、上述した紫外線感知チップ１２に加え、筐体４２と、天板４６と、集光部材としての凹面鏡４８とを有する。
　図９に示す例においては、天板４６が、紫外線感知チップ１２（紫外線感知シート１２ａ）を着脱自在に支持する支持部となる。すなわち、図９に示す例においては、筐体４２、天板４６および凹面鏡４８で、本発明の紫外線感知キット用ユニットが構成される。 An ultraviolet sensing kit 40 shown in FIG. 9 includes a housing 42, a top plate 46, and a concave mirror 48 as a condensing member in addition to the ultraviolet sensing chip 12 described above.
In the example shown in FIG. 9, the top plate 46 serves as a supporting portion that detachably supports the ultraviolet sensing chip 12 (ultraviolet sensing sheet 12a). That is, in the example shown in FIG. 9, the housing 42, the top plate 46 and the concave mirror 48 constitute the ultraviolet sensing kit unit of the present invention.
　図示例の紫外線感知キット４０において、筐体４２は、一例として、一面（上面）が開放する、立方体状の筐体である。上述した筐体１４と同様、筐体４２も内面が紫外線反射面であるのが好ましい。 In the illustrated ultraviolet sensing kit 40, the housing 42 is, for example, a cubic housing with one side (upper surface) open. Like the case 14 described above, the case 42 also preferably has an inner surface that reflects ultraviolet rays.
　筐体４２の開放面は、天板４６によって閉塞される。
　天板４６は、測定対象となる紫外線が透過可能な板材である。上述のように、紫外線感知キット４０においては、この天板４６が本発明における支持部であり、天板４６の上面に、紫外線感知チップ１２が載置される。なお、天板４６の上面とは、筐体４２とは逆側の面である。
　従って、天板４６の上面には、上述した下板１４ｂと同様の紫外線感知チップ１２の位置決め手段を設けるのが好ましい。 An open surface of the housing 42 is closed by a top plate 46 .
The top plate 46 is a plate material through which ultraviolet rays to be measured can pass. As described above, in the ultraviolet sensing kit 40 , the top plate 46 is the supporting portion of the present invention, and the ultraviolet sensing chip 12 is placed on the upper surface of the top plate 46 . The upper surface of the top plate 46 is the surface opposite to the housing 42 .
Therefore, it is preferable to provide the upper surface of the top plate 46 with positioning means for the ultraviolet sensing chip 12 similar to the lower plate 14b described above.
　天板４６は、測定対象となる紫外線が透過可能であれば、公知の板材が、各種、利用可能である。天板４６としては、一例として、石英ガラス、合成石英ガラス、ポリエチレン、ポリプロピレン、ポリアクリル、および、ポリ塩化ビニル等からなる板材が、好適に利用される。
　また、天板４６は、集光レンズ１６と同様、波長２２２ｎｍの紫外線の透過率が７０％以上であるのが好ましい。 Various known plate materials can be used for the top plate 46 as long as they can transmit the ultraviolet rays to be measured. As an example of the top plate 46, a plate material made of quartz glass, synthetic quartz glass, polyethylene, polypropylene, polyacryl, polyvinyl chloride, or the like is preferably used.
Further, like the condensing lens 16, the top plate 46 preferably has a transmittance of 70% or more for ultraviolet rays having a wavelength of 222 nm.
　筐体４２の中には、反射面を天板４６に向けて凹面鏡４８が保持される。すなわち、上述のように、図９に示す紫外線感知キット４０においては、筐体４２が集光部材を保持する保持部材として作用する。
　凹面鏡４８には、制限はなく、測定対象となる紫外線を反射可能であれば、アルミニウム等の金属材料を蒸着した凹面鏡等、公知の各種の凹面鏡が利用可能である。また、凹面鏡は、測定対象となる紫外線を反射可能であれば、市販品も利用可能である。凹面鏡４８の市販品としては、杉藤社製の凹面鏡等が例示される。 A concave mirror 48 is held in the housing 42 with its reflective surface facing the top plate 46 . That is, as described above, in the ultraviolet sensing kit 40 shown in FIG. 9, the housing 42 acts as a holding member that holds the condensing member.
The concave mirror 48 is not limited, and various known concave mirrors such as a concave mirror deposited with a metal material such as aluminum can be used as long as it can reflect the ultraviolet rays to be measured. A commercially available concave mirror can also be used as long as it can reflect the ultraviolet rays to be measured. As a commercial product of the concave mirror 48, a concave mirror manufactured by Sugitoh Co., Ltd. is exemplified.
　図９に示す紫外線感知キット４０では、天板４６の所定位置に紫外線感知チップ１２を配置して、紫外線量の測定を行う。紫外線感知チップ１２は、紫外線感知シート１２ａが露出している面を、凹面鏡４８に向けて、天板４６に載置する。
　この状態で、図９に概念的に示すように、天板４６から測定対象となる紫外線ＵＶを筐体４２内に照射する。筐体４２内に入射した紫外線ＵＶは、凹面鏡４８によって反射、集光されて、紫外線感知チップ１２の紫外線感知シート１２ａに入射する。紫外線感知キット４０においても、このような紫外線ＵＶの照射を、所定時間、行うことにより、紫外線感知シート１２ａを発色させ、その発色濃度で、紫外線ＵＶの線量を測定する。 In the ultraviolet sensing kit 40 shown in FIG. 9, the ultraviolet sensing chip 12 is arranged at a predetermined position on the top plate 46 to measure the amount of ultraviolet rays. The ultraviolet sensing chip 12 is placed on the top plate 46 with the exposed surface of the ultraviolet sensing sheet 12 a facing the concave mirror 48 .
In this state, as conceptually shown in FIG. 9, ultraviolet rays UV to be measured are irradiated from the top plate 46 into the housing 42 . The ultraviolet rays UV entering the housing 42 are reflected and condensed by the concave mirror 48 and enter the ultraviolet sensing sheet 12 a of the ultraviolet sensing chip 12 . Also in the ultraviolet sensing kit 40, the ultraviolet sensing sheet 12a is colored by irradiating the ultraviolet radiation UV for a predetermined period of time, and the dose of the ultraviolet radiation UV is measured based on the coloring density.
　従って、図９に示す紫外線感知キット４０においても、集光部材である凹面鏡４８によって集光した紫外線ＵＶを紫外線感知シート１２ａに照射することで、見掛け上、紫外線感知シート１２ａの感度を、大幅に向上できる。
　その結果、紫外線感知キット４０においても、短時間の測定で、紫外線感知シート１２ａを十分に発色させて、迅速かつ正確に、紫外線量の測定を行うことができる。 Therefore, in the ultraviolet sensing kit 40 shown in FIG. 9 as well, by irradiating the ultraviolet sensing sheet 12a with ultraviolet rays UV condensed by the concave mirror 48, which is a condensing member, the apparent sensitivity of the ultraviolet sensing sheet 12a is significantly increased. can improve.
As a result, even in the ultraviolet sensing kit 40, it is possible to sufficiently develop the color of the ultraviolet sensing sheet 12a in a short time and measure the amount of ultraviolet rays quickly and accurately.
　凹面鏡４８を用いる紫外線感知キット４０では、上述のように、凹面鏡４８で集光した紫外線を、紫外線感知チップ１２の紫外線感知シート１２ａに照射することで、紫外線量の測定を行う。
　従って、先の例と同様、効率の良い測定を行うためには、凹面鏡４８によって集光した紫外線ができるだけ紫外線感知シート１２ａの全面のみに照射されるように、筐体４２の高さ、すなわち、凹面鏡４８と紫外線感知シート１２ａとの距離を設定するのが好ましい。言い換えれば、本発明の紫外線感知キット１０においては、筐体４２の高さに応じて、凹面鏡４８によって集光した光ができるだけ紫外線感知シート１２ａのみに照射されるように、凹面鏡４８の焦点距離を選択するのが好ましい。 In the ultraviolet sensing kit 40 using the concave mirror 48, the amount of ultraviolet rays is measured by irradiating the ultraviolet sensing sheet 12a of the ultraviolet sensing chip 12 with the ultraviolet rays condensed by the concave mirror 48, as described above.
Therefore, as in the previous example, in order to perform efficient measurement, the height of the housing 42, i.e., It is preferable to set the distance between the concave mirror 48 and the ultraviolet sensitive sheet 12a. In other words, in the ultraviolet sensing kit 10 of the present invention, the focal length of the concave mirror 48 is adjusted according to the height of the housing 42 so that the light condensed by the concave mirror 48 irradiates only the ultraviolet sensing sheet 12a as much as possible. preferably selected.
　なお、凹面鏡４８を用いる紫外線感知キット４０では、必ずしも、凹面鏡４８は、筐体４２の底面に当接している必要はない。すなわち、紫外線感知キット４０においては、凹面鏡４８は、筐体４２の高さ方向の中間に保持されてもよい。
　この際にも、凹面鏡４８によって集光した紫外線ができるだけ紫外線感知シート１２ａの全面のみに照射されるように、凹面鏡４８と紫外線感知シート１２ａとの距離を設定するのが好ましい。
　また、凹面鏡４８を用いる紫外線感知キット４０では、内側面で紫外線感知チップ１２を支持し、反射面を天板４６に対して傾けて凹面鏡４８を配置し、凹面鏡４８によって、測定する紫外線の光路を変更かつ集光して、紫外線感知シート１２ａに紫外線を照射するようにしてもよい。 In addition, in the ultraviolet sensing kit 40 using the concave mirror 48 , the concave mirror 48 does not necessarily need to be in contact with the bottom surface of the housing 42 . That is, in the ultraviolet sensing kit 40, the concave mirror 48 may be held in the middle of the housing 42 in the height direction.
Also in this case, it is preferable to set the distance between the concave mirror 48 and the ultraviolet sensing sheet 12a so that the ultraviolet rays condensed by the concave mirror 48 are irradiated only on the entire surface of the ultraviolet sensing sheet 12a as much as possible.
In addition, in the ultraviolet sensing kit 40 using the concave mirror 48, the ultraviolet sensing chip 12 is supported on the inner surface, the reflecting surface is inclined with respect to the top plate 46, and the concave mirror 48 is arranged. The ultraviolet rays may be irradiated onto the ultraviolet sensitive sheet 12a by changing and condensing the rays.
　集光部材として凹面鏡４８を用いる態様では、測定対象となる紫外線が透過可能な天板４６に変えて、図１０に概念的に示すような、紫外線感知チップ１２を支持する枠である支持枠５０を用いて、紫外線感知キットを構成してもよい。
　この支持枠５０は、凹面鏡４８による紫外線の集光部に紫外線感知チップ１２を着脱自在に支持する枠状の支持部５０ａを有し、この支持部５０ａを外枠５０ｂおよび梁５０ｃによって支持するものである。
　この支持枠５０を用いる紫外線感知キットは、支持枠５０における外枠５０ｂと、梁５０ｃと、支持部５０ａとの間から、筐体４２内に測定対象となる紫外線を導入する。 In an embodiment using a concave mirror 48 as a light condensing member, instead of the top plate 46 through which the ultraviolet rays to be measured pass, a support frame 50, which is a frame for supporting the ultraviolet sensing chip 12 as conceptually shown in FIG. may be used to construct an ultraviolet sensing kit.
The support frame 50 has a frame-shaped support portion 50a for detachably supporting the ultraviolet sensing chip 12 in the ultraviolet light condensing portion of the concave mirror 48. The support portion 50a is supported by an outer frame 50b and beams 50c. is.
The ultraviolet sensing kit using this support frame 50 introduces ultraviolet rays to be measured into the housing 42 from between the outer frame 50b, the beam 50c, and the support portion 50a of the support frame 50. As shown in FIG.
　このような支持枠５０を用いる紫外線感知キットは、筐体４２から支持枠５０を着脱可能にして、凹面鏡４８の清掃を容易に行えるようにするのが好ましい。 In an ultraviolet sensing kit using such a support frame 50, it is preferable to make the support frame 50 detachable from the housing 42 so that the concave mirror 48 can be easily cleaned.
　また、集光部材として凹面鏡４８を用いる態様においても、図７に示す枠体３６を用いる構成のように、脚部３２によって天板４６または支持枠５０を支持して、筐体４２ではなく枠体によって本発明の紫外線感知キットを構成してもよい。
　この際には、脚部３２に、公知の方法で凹面鏡４８を保持すればよい。脚部３２による凹面鏡４８の保持方法としては、一例として、貼着、治具を用いる方法、脚部３２から内方に突出部を設け、この突出部に凹面鏡を載置する方法、および、脚部３２に凹部を設け、この凹部に凹面鏡４８の端部を挿入する方法等が例示される。 Also in the embodiment using the concave mirror 48 as the light-condensing member, the legs 32 support the top plate 46 or the support frame 50 as in the configuration using the frame 36 shown in FIG. The body may constitute the ultraviolet sensing kit of the present invention.
In this case, the concave mirror 48 may be held on the leg portion 32 by a known method. Examples of methods for holding the concave mirror 48 by the legs 32 include sticking, a method using a jig, a method of providing a protrusion inward from the leg 32 and placing the concave mirror on this protrusion, and a method of placing the concave mirror on the protrusion. A method of providing a recess in the portion 32 and inserting the end of the concave mirror 48 into the recess is exemplified.
　さらに、本発明の紫外線感知キット（紫外線感知キット用ユニット）は、集光部材として、集光レンズ１６と凹面鏡４８とを併用してもよい。 Further, the ultraviolet sensing kit (ultraviolet sensing kit unit) of the present invention may use the condensing lens 16 and the concave mirror 48 together as the condensing member.
　以上、本発明の紫外線感知キット、紫外線測定方法、および、紫外線感知キット用ユニットについて詳細に説明したが、本発明は、上述の例に制限はされず、本発明の要旨を逸脱しない範囲において、各種の改良および変更を行ってもよいのは、もちろんである。 Although the ultraviolet sensing kit, the ultraviolet measuring method, and the ultraviolet sensing kit unit of the present invention have been described in detail above, the present invention is not limited to the above examples, and within the scope of the present invention, Of course, various improvements and modifications may be made.
