Non-Polarizing
Plate Beamsplitters

IiBeamsplitters zenza kanye oko igama lazo likutshoyo, zahlula umqadi kumlinganiselo omiselweyo kumacala amabini.Ukongeza i-beamsplitters ingasetyenziselwa umva ukudibanisa imiqadi emibini eyahlukeneyo ibe yinto enye.I-beamsplitters eqhelekileyo isetyenziswa ngokuqhelekileyo kunye nemithombo yokukhanya engabonakaliyo njengendalo okanye i-polychromatic, iyahlula i-beam ngepesenti yokuqina, njenge-50% yokuhanjiswa kunye ne-50% yokubonisa, okanye i-30% yokudluliselwa kunye ne-70% yokubonisa.I-Dichroic beamsplitters yahlula ukukhanya okungenayo ngobude be-wavelength kwaye idla ngokusetyenziswa kwizicelo ze-fluorescence ukwahlula iindlela zokuvuselela kunye nokukhupha, ezi zixhobo zibonelela ngomlinganiselo wokwahlula oxhomekeke kubude bokukhanya kwesiganeko kwaye ziluncedo ekudibaniseni / ukwahlula imiqadi yelaser eyahlukeneyo. imibala.

Iibeamsplitters zihlala zihlelwa ngokokwakhiwa kwazo: i-cube okanye ipleyiti.I-plate beamsplitter luhlobo oluqhelekileyo lwe-beamsplitter eyenziwe nge-substrate yeglasi encinci kunye ne-optical coating elungiselelwe i-angle ye-45 ° yesiganeko (AOI).Iibeamsplitters zepleyiti eziqhelekileyo zahlula ukukhanya kwesiganeko ngomlinganiselo ochaziweyo ozimeleyo kwi-wavelength yokukhanya okanye i-polarization state, ngelixa i-polarizing plate beamsplitters ziyilelwe ukuphatha i-S kunye ne-P ye-polarization yamazwe ngokwahlukileyo.

Izinto eziluncedo zeplate beamsplitter zingaphantsi kwechromatic aberration, ukufunxeka okuncinci ngenxa yeglasi encinci, uyilo oluncinci kunye nolukhaphukhaphu xa kuthelekiswa ne-cube beamsplitter.Ukungalungi kweplate beamsplitter yimifanekiso yesiporho eveliswa ngokuba nokukhanya okubonakaliswe kuyo yomibini imiphezulu yeglasi, ukufuduswa komqadi osecaleni ngenxa yobunzima beglasi, ubunzima bokunyuka ngaphandle koguquko, kunye novelwano lwabo ekukhanyeni kwepolarized.

Imiqadi yethu yepleyiti inomphezulu ogqunywe ngaphambili omisela umyinge wokwahlulahlula umqadi ngelixa indawo yangasemva idityanisiwe kwaye i-AR igqunywe.I-Wedged Beamsplitter Plate yenzelwe ukwenza iikopi ezininzi ezincitshisiweyo zomqadi omnye wokufaka.

Ukunceda ukunciphisa iziphumo ezingafunekiyo zokuphazamiseka (umzekelo, imifanekiso yesiporho) ebangelwa kukudibana kokukhanya okuvela kumphezulu ongaphambili nasemva we-optic, zonke ezi plate beamsplitters zine-antireflection (AR) yokwambathisa efakwe kumphezulu ongasemva.Le yokwambathisa yenzelwe wavelength efanayo yokusebenza njengoko beamsplitter ukutyabeka kumphezulu ngaphambili.Ngokumalunga ne-4% yesiganeko sokukhanya kwi-45 ° kwi-substrate engafakwanga iya kubonakala;ngokufaka i-AR yokwambathisa kwicala elingasemva le-beamsplitter, le pesenti iyancitshiswa ukuya kumyinge ongaphantsi kwe-0.5% kubude bobume boyilo lwengubo.Ukongeza kolu phawu, umphezulu ongemva wazo zonke iiplate zethu ezingqukuva zineentsimbi ze-arcmin ezingama-30, ke ngoko, iqhezu lokukhanya elibonakaliswayo kulo mphezulu we-AR-coated liya kuphambuka.
I-Paralight Optics inikezela ngeeplate beamsplitters ezikhoyo zombini iimodeli ze-polarizing kunye ne-non-polarizing.Iibeamsplitters zepleyiti eziqhelekileyo ezingezo-polarizing zahlula ukukhanya kwesiganeko ngomlinganiselo ochaziweyo ozimeleyo kwi-wavelength yokukhanya okanye imo ye-polarization, kanti i-polarizing plate beamsplitters ziyilelwe ukuphatha i-S kunye ne-P ye-polarization state ngokwahlukileyo.

Ipleyiti yethu engeyiyo-polarizingbeamsplitterszenziwe yi-N-BK7, i-Silica eFused, i-Calcium Fluoride kunye ne-Zinc Selenide egubungela i-UV ukuya kwi-MIR ububanzi be-wavelength.Sikwanikezelaiibeamsplitters zokusetyenziswa nge-Nd:YAG wavelengths (1064 nm kunye ne532 nm).Ngolunye ulwazi malunga neengubo ze-beamsplitters ezingezona-polarizing ngu-N-BK7, nceda ujonge ezi grafu zilandelayo kwiimbekiselo zakho.

I-Non-Polarizing Plate Beamsplitter

Iiplate beamsplitters ziquka ipleyiti yeglasi ebhityileyo ethe yaqatywa kumphezulu wokuqala we-substrate.Uninzi lweeplate beamsplitters lubonisa i-anti-reflection coating kwindawo yesibini ukususa izibonakaliso zeFresnel ezingafunekiyo.Iiplate beamsplitters zihlala ziyilelwe i-45 ° AOI.Kwii-substrates ezine-1.5 index of refraction kunye ne-45 ° AOI, umgama wokutshintsha kwe-beam (d) unokuqikelelwa kusetyenziswa i-equation kumzobo osekhohlo.
