Description

Oppfinnelsens gjenstand er et fotometerhode til inndypning i flytende medier og som har en lyssender og en lysmottager overfor dens i et plan befinnende flater for uttreden respektiv inntreden av lysenergi fra lyssenderen resp. i lysmottageren er anordnet et speil. The object of the invention is a photometer head for immersion in liquid media and which has a light transmitter and a light receiver facing it in flat surfaces for the exit or entry of light energy from the light transmitter or a mirror is arranged in the light receiver.

Fotometerhoder av nevnte type er kjent fra den franske patentsøknad nr. 2.297.415. Photometer heads of the aforementioned type are known from French patent application No. 2,297,415.

Oppfinnelsens oppgave består i å tilveiebringe et fotometerhode hvormed med lang lysvei i målerommet målevolumene kan holdes små. The task of the invention is to provide a photometer head with which, with a long light path in the measuring room, the measuring volumes can be kept small.

Oppgaven løses ved hjelp av et fotometerhode som erkarakterisert vedat minst en lyssender og en lysmottager (et par) er anordnet i en holder som har støtter for en speilholder som minst har to speiler som er anordnet hellende mot hverandre og med avstand i forhold til den tilhørende lyssender resp. lysmottager at ved hjelp av støttene til speilholderen og holderen begrenses et åpent rom hvori det munner en kanal som befinner seg i holderen mellom lyssender og lysmottager og speilholderen er utstyrt med en åpning som ligger overfor kanalen. The task is solved with the help of a photometer head which is characterized by at least one light transmitter and one light receiver (a pair) being arranged in a holder which has supports for a mirror holder which has at least two mirrors which are arranged inclined towards each other and at a distance in relation to the associated light transmitter or light receiver that with the help of the supports for the mirror holder and the holder, an open space is limited into which a channel that is located in the holder opens between the light emitter and the light receiver and the mirror holder is equipped with an opening that lies opposite the channel.

I en utførelsesform er det i holderen parallelt til kanalen minst anordnet to par av lyssender og lysmottager og på speilholderen rundt åpningen minst to par av respektivt to. speiler som er helt mot hverandre således at de inneslutter en vinkel a på 90°. Lyssender og lysmottager kan være utstyrt med selvfokuserende optiske innretninger. In one embodiment, at least two pairs of light emitters and light receivers are arranged in the holder parallel to the channel, and on the mirror holder around the opening at least two pairs of respectively two. mirrors which are opposite each other so that they enclose an angle a of 90°. Light transmitter and light receiver can be equipped with self-focusing optical devices.

I det følgende skal oppfinnelsen forklares nærmere under henvisning til en utførelsesmåte som er vist på tegningen. In the following, the invention will be explained in more detail with reference to an embodiment shown in the drawing.

Figur 1 viser fotometerhodet, nemlig som .snitt I-l på figur 2 og figur 2 snittet II-II på figur 1. Figure 1 shows the photometer head, namely as section I-1 in figure 2 and figure 2 section II-II in figure 1.

Ved fotometerhodet til inndypning i flytende medier er i en holder 1 av kunststoff, kunstharpiks, metall osv. an ordnet parene av respektivt en lyssender 2 og en lysmottager 3. Holderen 1 har støtter 6 for en speilholder 7 som bærer speil 8 som befinner seg nøyaktig overfor den tilhørende lyssender 2 resp. lysmottager 3 og således er helt mot hverandre at de inneslutter en vinkel'a på 90°. Lyssender 2 og lysmottager 3 er hensiktsmessig anordnet aksesymmetrisk til hverandre og konsentrisk rundt en kanal 4. Denne kanal 4 munner et i åpent rom 5 som begrenses ved holderen 1, støttene 6 og speilholder 7. Speilholderen 7 er utstyrt med en åpning 9 som ligger overfor kanalen 4 og rundt hvilke likeledes aksesymmetrisk er anordnet speil 8. Som lyssender 2 egner det seg lyskilder som lam-per lysdioder eller glassfiberlysledere og som lysmottager 3 fotodioder eller likeledes glassfiberlysledere. I figur 1 viser lysleder 2,3 hvis ender er utstyrt med selvfokuserende optiske innretninger 10,11. 12 antyder et kar med flytende medium, hvori fotometerhodet er inndyppet. Bok-stavene a til c skal antyde hvilke lyssender 2 og lysmottager 3 resp. danner et par. At the photometer head for immersion in liquid media, the pairs of respectively a light transmitter 2 and a light receiver 3 are arranged in a holder 1 made of plastic, synthetic resin, metal, etc. The holder 1 has supports 6 for a mirror holder 7 which carries mirror 8 which is located exactly opposite the associated light transmitter 2 or light receiver 3 and are thus completely opposite each other that they include an angle'a of 90°. Light transmitter 2 and light receiver 3 are suitably arranged axisymmetric to each other and concentrically around a channel 4. This channel 4 opens into an open space 5 which is limited by the holder 1, the supports 6 and mirror holder 7. The mirror holder 7 is equipped with an opening 9 which lies opposite the channel 4 and around which mirror 8 is also axisymmetrically arranged. As light transmitter 2, light sources that illuminate light-emitting diodes or glass fiber light guides and as light receivers 3 photodiodes or likewise glass fiber light guides are suitable. Figure 1 shows light conductors 2,3 whose ends are equipped with self-focusing optical devices 10,11. 12 suggests a vessel of liquid medium in which the photometer head is immersed. The letters a to c shall indicate which light transmitter 2 and light receiver 3 respectively. form a pair.

Lyssenderen 2 sender lysbunter inn i det åpne rom 5.The light emitter 2 sends light beams into the open space 5.

Etter passering gjennom det flytende mediet kommer lysbun-ten over speil 8 til lysmottageren 3, hvorved det fremkom-mer en spesiell lang lysvei. Ved siden av hvitt lys kan det også føres forskjelligfarget lys over korresponderende lyslederpar 2a, 3a, 2b, 3b således at det tidsmessig parallelt kan gjennomføres bikromatisk eller også polykro-matiske fotometermålinger. Fluorescens- eller kjemolumi-nescensmålinger kan likeledes gjennomføres. Ved lang lysvei i det åpne målrom 5 kan det flytende mediums volum holdes lite. Over kanal 4 kan flytende medium tilføres respektivt ved avsugning sørges for at det åpne rom 5 After passing through the liquid medium, the light beam comes over mirror 8 to the light receiver 3, whereby a special long light path is produced. In addition to white light, differently colored light can also be passed over corresponding pairs of light guides 2a, 3a, 2b, 3b so that bichromatic or polychromatic photometer measurements can be carried out in parallel in time. Fluorescence or chemiluminescence measurements can also be carried out. With a long light path in the open target space 5, the volume of the liquid medium can be kept small. Above channel 4, liquid medium can be supplied respectively by suction, ensuring that the open space 5

er fylt fullstendig med flytende medium. Fotometerhodet har dessuten fordelen med enkel rensning.- is completely filled with liquid medium. The photometer head also has the advantage of easy cleaning.
