Depolarizing
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. Tsis tas li ntawd, beamsplitters tuaj yeem siv rov qab los ua ke ob kab sib txawv rau hauv ib qho. 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 beamsplitters tshwj xeeb yog tswj kom tsis txhob hloov S thiab P polarization xeev ntawm lub teeb tuaj, txawm li cas los xij nrog cov tsis muaj polarizing beamsplitters, muab lub teeb pom kev sib txawv polarized, tseem yuav muaj qee qhov teebmeem polarization. Peb depolarizing beamsplitters yuav tsis rhiab heev rau polarization ntawm qhov teeb meem beam, qhov sib txawv ntawm kev xav thiab kev xa mus rau S- thiab P-pol yog tsawg dua 6%, lossis tsis muaj qhov sib txawv ntawm kev xav thiab kev xa mus rau S- thiab P-pol ntawm qee qhov tsim wavelengths. Thov xyuas cov duab hauv qab no rau koj cov ntaub ntawv siv.

Depolarizing Cube Beamsplitter

Txhua lub voos xwmfab yog tsim los ntawm N-BK7 thiab tsim los rau cov nqaj qis qis. Ib qho kev cuam tshuam saum npoo kuj zam cov duab dab. Lub hydrid depolarizing beamsplitter txheej yog siv rau lub hypotenuse ntawm ib qho ntawm ob lub prisms uas ua rau lub voos xwmfab. Tom qab ntawd, cement yog siv los khi ob lub prism halves ua ke.
