Kutagira inkingi
Isahani yamashanyarazi

Amashanyarazi akora neza icyo izina ryabo risobanura, ugabanye urumuri ku kigereranyo cyagenwe mu byerekezo bibiri.Byongeye kandi, urumuri rushobora gukoreshwa muburyo bwo guhuza ibiti bibiri bitandukanye murimwe.Amashanyarazi asanzwe akoreshwa hamwe nisoko yumucyo utagira inkingi nka naturel cyangwa polychromatique, bagabanije urumuri nijanisha ryimbaraga, nko kwanduza 50% na 50%, cyangwa 30% kwanduza no 70%.Dichroic beamsplitters igabanya urumuri rwinjira nuburebure bwumuraba kandi bikunze gukoreshwa mubisabwa na fluorescence kugirango batandukane inzira zishimishije n’ibyuka bihumanya ikirere, ibyo biti bitanga ibipimo bigabanywa biterwa nuburebure bwumucyo wibyabaye kandi bifite akamaro muguhuza / kugabana urumuri rwa lazeri zitandukanye. amabara.

Amashanyarazi akoreshwa mubyiciro akurikije ibyubatswe: cube cyangwa isahani.Isahani yamashanyarazi ni ubwoko busanzwe bwibiti bigizwe nibirahuri bito byikirahure hamwe na optique ya optique yatunganijwe neza kuri 45 ° yibyabaye (AOI).Isahani isanzwe yerekana itandukanyirizo ryumucyo wagereranije nigipimo cyagenwe kidashingiye ku burebure bwumucyo cyangwa imiterere ya polarisiyasi, mugihe ibyuma byerekana ibyapa byashizweho kugirango bifate leta ya S na P.

Ibyiza bya plaque yamashanyarazi ni gake ya chromatic aberration, kutinjira cyane kubera ibirahuri bike, ibishushanyo bito kandi byoroshye ugereranije na cube beamsplitter.Ibibi bya plaque yamashanyarazi ni amashusho yizimu yakozwe no kugira urumuri rugaragarira hejuru yikirahure cyombi, kwimura uruhande rwibiti bitewe nubunini bwikirahure, ingorane zo kuzamuka nta guhindagurika, hamwe no kumva urumuri rwinshi.

Amasahani yacu yamashanyarazi afite ubuso bwimbere bugena igipimo cyo kugabana ibiti mugihe ubuso bwinyuma bwahujwe na AR.Isahani ya Wedged Beamsplitter yashizweho kugirango ikore kopi nyinshi zegeranye za kamwe kamwe kinjiza.

Kugira ngo ufashe kugabanya ingaruka zitifuzwa (urugero, amashusho yizimu) yatewe no gukorana kwurumuri rugaragarira hejuru yimbere ninyuma ya optique, ibyo byapa byose byerekana ibyuma bifite antireflection (AR) byashyizwe hejuru yinyuma.Iyi shitingi yagenewe uburebure buringaniye bwo gukora nkuburebure bwa beamsplitter hejuru yimbere.Hafi ya 4% yibyabaye kuri 45 ° kuri substrate idafunze bizagaragazwa;ukoresheje AR igipfundikizo cya AR kuruhande rwinyuma rwibiti, iyi ijanisha ryaragabanutse kugera ku kigereranyo kiri munsi ya 0.5% kumurongo wuburebure bwa coating.Usibye iyi miterere, ubuso bwinyuma bwibibaho byose byerekana uruziga rufite uruziga rwa arcmin 30, kubwibyo, igice cyumucyo kigaragarira kuri ubu buso bwa AR butandukanijwe.
Paralight Optics itanga amasahani yamashanyarazi aboneka haba muburyo bwa polarisiyonike kandi butari polarize.Amashanyarazi asanzwe adafite polarize agabanya urumuri rwabaye ku kigereranyo cyagenwe kidashingiye ku burebure bw’umucyo cyangwa imiterere ya polarisiyasi, mu gihe ibyapa byerekana ibyapa byashizweho kugira ngo bitandukane na S na P.

Isahani yacu idafite polarizekumurikabahimbwe na N-BK7, Fused Silica, Kalisiyumu Fluoride na Zinc Selenide bitwikiriye UV kugeza kuri MIR.Turatanga kandiurumuri rwo gukoresha hamwe na Nd: Uburebure bwa YAG (1064 nm na 532 nm).Kumakuru amwe yerekeye gutwikisha ibiti bidafite inkingi ya N-BK7, nyamuneka reba ibishushanyo bikurikira uhereye aho werekeza.

Amashanyarazi adafite inkingi

Isahani yamashanyarazi igizwe nisahani yoroheje, isahani yikirahure yatwikiriwe hejuru yambere ya substrate.Ibyapa byinshi byerekana isahani irwanya anti-reaction hejuru ya kabiri kugirango ikureho ibitekerezo bya Fresnel udashaka.Isahani yamashanyarazi ikorerwa kuri 45 ° AOI.Kuri substrates hamwe na 1.5 yerekana kugabanuka hamwe na 45 ° AOI, intera ihindagurika (d) irashobora kugereranywa ukoresheje ikigereranyo mugushushanya ibumoso.
