Depolarizing
Phaj Beamsplitters

Beamsplitters yog cov khoom siv kho qhov muag uas faib lub teeb hauv ob qho kev qhia.Piv txwv li, lawv feem ntau yog siv nyob rau hauv interferometers nyob rau hauv thiaj li yuav tau ib tug beam los cuam tshuam rau nws tus kheej.Feem ntau muaj ntau ntau hom beamsplitters: phaj, lub voos xwmfab, pellicle thiab polka dot beamsplitters.Tus qauv beamsplitter faib cov nqaj los ntawm feem pua ntawm kev siv zog, xws li 50% kev sib kis thiab 50% kev xav lossis 30% kev xa mus thiab 70% kev xav.Non-polarizing beamsplitters tshwj xeeb yog tswj kom tsis txhob hloov S thiab P polarization xeev ntawm lub teeb tuaj.Polarizing beamsplitters yuav xa P polarized lub teeb thiab cuam tshuam S polarized lub teeb, tso cai rau cov neeg siv ntxiv lub teeb polarized rau hauv qhov muag pom.Dichroic beamsplitters faib lub teeb los ntawm wavelength thiab feem ntau siv nyob rau hauv daim ntawv thov fluorescence cais excitation thiab emission txoj kev.

Txawm hais tias tsis yog-polarizing beamsplitters yog tsim los tsis hloov S thiab P polarization xeev ntawm lub teeb tuaj, lawv tseem rhiab rau lub teeb polarized, uas txhais tau tias tseem yuav muaj qee qhov cuam tshuam polarization yog tias tsis yog-polarizing beamsplitters tau muab lub teeb pom kev zoo polarized. .Txawm li cas los xij peb depolarizing beamsplitters yuav tsis nkag siab rau polarization ntawm cov teeb meem kab teeb, qhov sib txawv ntawm kev xav thiab kev xa mus rau S- thiab P-pol.tsawg dua 5%, lossis tsis muaj qhov sib txawv ntawm kev xav thiab kev sib kis rau S- thiab P-pol ntawm qee qhov qauv tsim wavelengths.Thov xyuas cov duab hauv qab no rau koj cov ntaub ntawv siv.

Paralight Optics muaj ntau yam ntawm optical beamsplitters.Peb cov phaj beamsplitters muaj coated pem hauv ntej nto uas txiav txim siab lub beam splitting ratio thaum lub sab nraub qaum yog wedged thiab AR coated thiaj li yuav txo tau ghosting thiab cuam tshuam los.Peb lub voos xwmfab beamsplitters muaj nyob rau hauv polarizing lossis tsis-polarizing qauv.Pellicle beamsplitters muab cov khoom zoo tshaj plaws ntawm kev sib kis ntawm lub ntsej muag thaum tshem tawm cov nqaj offset thiab ghosting.Dichroic beamsplitters nthuav tawm beamsplitting zog uas yog nyob ntawm wavelength.Lawv muaj txiaj ntsig zoo rau kev sib txuas / cais cov kab teeb laser ntawm cov xim sib txawv.
