本発明は顕微鏡用投影装置、特に無１ｌＩｌ薇投射面ｆ
ｄｆｔＬ、、て光透過が行われる投影装置に関連する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a projection device for a microscope, particularly a projection device with no projection surface f.
dftL, is related to a projection device in which light transmission is performed.
投射面は適度３４の方法によって粒状性のない無網目状
６ｖｃする。第１の方法では、＃い１例えば厚さ０２酊
のワックス層を含む無九沢拡肢スクリーンを２板の平行
ガラス板間に配置する。The projection surface is made into a non-mesh 6vc without graininess by a moderate method of 34. In the first method, a #1, e.g., 0.2 mm thick wax expansion screen containing a wax layer is placed between two parallel glass plates.
第２の方法では、２枚の無光沢拡散スクリーンを使用し
、これらのスクリーンを比較的低速度で相互移動するが
、この無光沢面間の距ｌｌｌは１１（９）
の数分の−８例えばＱ、２總である。第３の方法では、
１枚の無光沢スクリーンを使用し、これを比較的迅速に
移動０例えば回転する。A second method uses two matte diffuser screens that are moved relative to each other at relatively low speeds, the distance lll between the matte surfaces being a fraction of 11 (9) -8 For example, Q, 2 So. In the third method,
A single matte screen is used and it is moved, eg rotated, relatively quickly.
上記３方法はそれぞれ投影スクリーンにおける光の拡散
及び／又は屈折を阻止し顕微鏡の小さい射出瞳から発射
された光は、投影スクリーン上の種々の点から観察者の
眼に入射するが他の種々の点から発射された光は観察者
の眼に達しないようにするものである。Each of the above three methods prevents the diffusion and/or refraction of light at the projection screen, so that the light emitted from the small exit pupil of the microscope enters the observer's eye from various points on the projection screen, but at various other points. The light emitted from the point is prevented from reaching the observer's eyes.
又顕微鏡用透過光投影装置の場合には、投影面が中心、
即ち光軸の方向で観察する時には投影面の縁部に向って
光度が減少する問題がある。In addition, in the case of a transmitted light projection device for a microscope, the projection surface is the center,
That is, when observing in the direction of the optical axis, there is a problem that the luminous intensity decreases toward the edge of the projection surface.
この光度低下は、無光沢拡散スクリーンを使用すると入
射ビームに向けて散乱光、即ち拡散光の最大値が増加し
、又縁部に向けてこの最大値が減少し、この効果が光軸
に対する入射角度の増加につれて増大する事実によるも
のである。This reduction in luminosity is due to the fact that the use of a matte diffuser screen increases the maximum value of scattered light, or diffused light, toward the incident beam and decreases this maximum value toward the edges, an effect that This is due to the fact that it increases with increasing angle.
上記の光度低下を除去するため、中心から画集する時に
は、顕微鏡の射出瞳に対向する投影面側に従来フレネル
レンズが使用された。フレネルレンズは、もしこの焦点
距離が射出瞳からの距離に等しければ、射出瞳から発射
されるＵ−ムを平行にし、又もし顕微鏡の射出Ｉからの
距離がレンズの焦点距離より大きいとビームを収束光線
ＶＣする。In order to eliminate the above-mentioned reduction in luminous intensity, a Fresnel lens has conventionally been used on the projection surface side facing the exit pupil of the microscope when collecting images from the center. A Fresnel lens parallelizes the beam emitted from the exit pupil if this focal length is equal to the distance from the exit pupil, and parallelizes the beam if the distance from the exit I of the microscope is greater than the focal length of the lens. Convergent ray VC.
映像特性、Ｐ口ち像の鮮鋭度は、投影面で像を無網目状
にする上記第３法中の１つにフレネルレンズを使用する
と鮮鋭度が低下することを本発明者は発見した。事実、
きらつき効果を除去するｔ防装置のない時よりも１象の
鮮鋭度ＩＳｔ悪い。The present inventors have discovered that the sharpness of the image characteristic, P-mouth image, is reduced when a Fresnel lens is used in one of the third methods described above to make the image mesh-free on the projection plane. fact,
The sharpness is one image worse than without the anti-glare device that removes the glitter effect.
本発明の一目的は、像の粒状性改良装置を使用するにも
掬らず良好な像鮮鋭度を示す顧＃鏡用投彰装置を提供す
ることにある。One object of the present invention is to provide a projection device for a mirror that exhibits good image sharpness without being skimmed even when an image graininess improving device is used.
本発明の特定目的は１粒状性改良装置が、比較的低速度
で相互移動する２枚の無光沢拡散スクリーンを含み、良
好な像鮮鋭度を示す投影装置を提供することにある。A particular object of the present invention is to provide a projection device in which one graininess improvement device includes two matte diffusion screens that move relative to each other at relatively low speeds and exhibit good image sharpness.
本発明によると、像の粒状性のない投影面。According to the invention, a projection surface without image graininess.

。In other words, it is a mirror projection device in which light is sent from the exit pupil of the microscope through a meshless projection surface, and a biconvex lens is placed near the projection surface, so that the light beam emitted from the exit pupil of the mirror becomes parallel. Alternatively, an integrated microscope useful device can be obtained.
本発明の明細省中の用語”両凸レンズ１は旧の両凸レン
ズを！１床する。The term "biconvex lens 1" in the specification of the present invention replaces the old biconvex lens.
との両凸レンズは、顧は鏡の射出瞳から遠い投影面側に
配置してもよいが顕微鏡の射出瞳と同じ投影面１４０す
こ配置するとよい。この配置は。The biconvex lens may be placed on the projection surface side far from the exit pupil of the mirror, but it is preferably placed on the projection surface 140, which is the same as the exit pupil of the microscope. This arrangement is.

るので。This is preferable in that reflection on the lens surface caused by external light 1, such as light incident from a window or indoor lighting, can be avoided by passing it through a diffusion screen. The operator can use the pointer of the projection device on the diffuser screen to change the color from the side helmet of the screen without causing any distortion of the image. Because I can understand it.
拡散もスクリーン上で細隼の一察かで色る。The spread also changes depending on the moment when Hossa Hayabusa appears on the screen.
