I-Polarizing Cube Beamsplitters

IiBeamsplitters zenza kanye oko igama lazo likutshoyo, zahlula umqadi kumlinganiselo omiselweyo kumacala amabini.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.Iibeamsplitters zetyhubhu zenziwe ngeeprism ezimbini ze-engile yasekunene ezidityaniswe kunye kwi-hypotenuse kunye nokwaleka okubonisayo phakathi.Umphezulu we-hypotenuse weprism enye uqatywe, kwaye iiprism ezimbini zidityaniswe kunye ukuze zenze i-cubic shape.Ukuze ugweme ukonakalisa i-samente, kucetyiswa ukuba ukukhanya kudluliselwe kwi-prism edibeneyo, ehlala ibonisa uphawu lokubhekisela kumhlaba ophantsi.
Izinto eziluncedo ze-cube beamsplitters zibandakanya ukukhwela lula, ukuqina kwe-optical coating kuba iphakathi kwemiphezulu emibini, kwaye akukho mifanekiso yesiporho ukusukela oko ukubonakaliswa kwakusasaza ngasemva kwicala lomthombo.Ukungalungi kwetyhubhu kukuba i-bulkier & inzima kunezinye iindidi ze-beamsplitters kwaye ayigubungeli ububanzi be-wavelength njengepellicle okanye i-polka dot beamsplitters.Nangona sibonelela ngeendlela ezininzi ezahlukeneyo zokwaleka.Kwakhona imiqadi yetyhubhu kufuneka isetyenziswe kuphela ngemiqadi edityanisiweyo kuba ukuguquguquka okanye ukwahluka kwemiqadi kunegalelo ekuthotyweni komgangatho womfanekiso.

IParalight Optics ibonelela ngeemitha zetyhubhu ezifumanekayo zombini iimodeli zepolarizing kunye nezingezopholarizing.Iibeamsplitters zetyhubhu ezingapholalisi ziyilelwe ukwahlula ukukhanya kwesiganeko ngomlinganiselo ochaziweyo ozimeleyo kubude bokukhanya okanye imo yepolarization.Nangona i-polarizing beamsplitters iya kuhambisa i-P polarized light kwaye ibonise ukukhanya kwe-S polarized evumela umsebenzisi ukuba afake ukukhanya kwe-polarized kwi-optical system, ingasetyenziselwa ukwahlula ukukhanya okungabonakaliyo kwi-50/50 ratio, okanye kwi-polarization yokwahlula izicelo ezifana ne-optical isolation.

I-Polarizing Cube Beamsplitter

Qaphela: I-extinction ratio (ER) ichazwa njengomlinganiselo wokukhanya okudlulisiweyo kwe-p-polarized ukukhanya kwe-s-polarized, okanye i-Tp / Ts.Nangona kunjalo, kubalulekile ukuqaphela ukuba i-Tp/Ts ayidli ngokulingana nomlinganiselo wokukhanya okubonakalisiweyo kwe-s-polarized ukukhanya kwe-p-polarized, okanye i-Rs/Rp.Ngokwenyani umlinganiselo we Tp/Ts (ER) usoloko ungcono kunomlinganiselo we Rs/Rp.Oku kungenxa yokuba iibeamsplitters zisebenza ngokufanelekileyo ekuboniseni i-s-polarization kodwa azisebenzi kangako ekuthinteleni i-p-polarization ukuba ingabonakali, oko kukuthi, ukukhanya okudluliswayo kuphantse kungabikho s-polarization, kodwa ukukhanya okubonakalisiweyo akukhululekanga ngokupheleleyo kwi-p-polarization.
