Polarizing Cube Beamsplitters

Beamsplitters ua raws nraim li lawv lub npe cuam tshuam, faib ib lub nqaj ntawm qhov sib piv ntawm ob qho kev qhia. Cov qauv beamsplitters feem ntau siv nrog cov teeb pom kev tsis zoo xws li ntuj lossis polychromatic, lawv faib cov nqaj los ntawm feem pua ​​​​ntawm kev siv, xws li 50% kev sib kis thiab 50% kev xav, lossis 30% kev xa mus thiab 70% kev xav. Dichroic beamsplitters faib lub teeb nkag los ntawm lub teeb thiab feem ntau siv rau hauv daim ntawv thov fluorescence kom cais cov excitation thiab emission paths, cov beamsplitters muaj ib tug splitting ratio uas yog nyob ntawm lub wavelength ntawm qhov teeb meem teeb thiab muaj txiaj ntsig rau kev sib txuas / splitting laser beams sib txawv. xim.

Beamsplitters feem ntau raug faib raws li lawv cov kev tsim kho: lub voos xwmfab lossis phaj. Lub voos xwmfab beamsplitters yog qhov tseem ceeb ntawm ob lub kaum sab xis prisms cemented ua ke ntawm lub hypotenuse nrog ib feem ntawm cov txheej txheej hauv nruab nrab. Lub hypotenuse nto ntawm ib lub prism yog coated, thiab ob lub prisms yog cemented ua ke kom lawv tsim ib lub cubic duab. Txhawm rau kom tsis txhob ua kom puas cov cement, nws raug nquahu kom lub teeb xa mus rau hauv cov coated prism, uas feem ntau muaj cov cim siv rau hauv av.
Qhov zoo ntawm lub voos xwmfab beamsplitters suav nrog kev yooj yim mounting, durability ntawm optical txheej vim nws nyob nruab nrab ntawm ob qhov chaw, thiab tsis muaj dab dluab txij li thaum lub reflections propagate rov qab mus rau hauv cov kev taw qhia ntawm qhov chaw. Disadvantages ntawm lub voos xwmfab yog tias nws yog bulkier & hnyav dua li lwm hom beamsplitters thiab tsis npog raws li qhov dav ntawm lub wavelength ntau yam li pellicle lossis polka dot beamsplitters. Txawm hais tias peb muaj ntau yam kev xaiv txheej txheej. Tsis tas li ntawd, lub voos xwmfab beamsplitters yuav tsum tsuas yog siv nrog cov kab teeb sib sib zog nqus txij li kev sib txuas los yog cov kab sib txawv ua rau muaj txiaj ntsig zoo rau cov duab tsis zoo.

Paralight Optics muaj lub voos xwmfab beamsplitters muaj ob qho tib si polarizing thiab tsis-polarizing qauv. Non-polarizing lub voos xwmfab beamsplitters yog tsim los faib qhov teeb meem teeb meem los ntawm ib qho piv txwv uas yog ywj siab ntawm lub teeb lub wavelength los yog polarization xeev. Whereas polarizing beamsplitters yuav xa P polarized lub teeb thiab muaj kev cuam tshuam S polarized lub teeb tso cai rau tus neeg siv ntxiv lub teeb polarized rau hauv qhov kho qhov muag, lawv tuaj yeem siv los faib lub teeb tsis muaj polarized ntawm 50/50 piv, lossis rau kev sib cais polarization xws li optical cais.

Polarizing Cube Beamsplitter

Lus Cim: Qhov piv txwv ntawm kev ploj tuag (ER) txhais tau tias yog qhov piv ntawm qhov sib kis ntawm p-polarized lub teeb rau s-polarized lub teeb, lossis Tp / Ts. Txawm li cas los xij, nws yog ib qho tseem ceeb kom paub tias Tp / Ts feem ntau tsis sib npaug rau qhov piv ntawm cov teeb pom kev s-polarized rau p-polarized lub teeb, lossis Rs / Rp. Raws li qhov tseeb qhov sib piv ntawm Tp / Ts (ER) yuav luag ib txwm zoo dua li qhov piv ntawm Rs / Rp. Qhov no yog vim hais tias beamsplitters feem ntau ua tau zoo ntawm kev xav txog s-polarization tab sis lawv tsis zoo li tiv thaiv p-polarization los ntawm kev xav, piv txwv li, lub teeb kis tau yuav luag tsis muaj s-polarization, tab sis lub teeb pom kev tsis yog dawb ntawm p-polarization.
