Tsis-Polarizing
Phaj 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 phaj beamsplitter yog ib hom ntawm beamsplitter uas yog tsim los ntawm cov iav nyias nyias nrog cov txheej txheem kho qhov muag kom zoo rau 45 ° kaum ntawm qhov xwm txheej (AOI).Txheem phaj beamsplitters faib teeb meem teeb meem los ntawm qhov piv txwv uas yog ywj siab ntawm lub teeb lub wavelength los yog polarization xeev, thaum polarizing phaj beamsplitters yog tsim los kho S thiab P polarization xeev txawv.

Qhov zoo ntawm lub phaj beamsplitter yog tsawg chromatic aberration, tsawg nqus vim iav tsawg, me thiab sib zog tsim piv rau lub voos xwmfab beamsplitter.Qhov tsis zoo ntawm lub phaj beamsplitter yog cov duab dab uas tsim los ntawm kev muaj lub teeb pom kev tawm ntawm ob qhov chaw ntawm lub iav, kev hloov pauv ntawm cov nqaj vim yog tuab ntawm iav, nyuaj rau mount yam tsis muaj deformation, thiab lawv rhiab heev rau lub teeb polarized.

Peb cov phaj beamsplitters muaj coated pem hauv ntej nto uas txiav txim siab lub beam splitting piv thaum lub sab nraub qaum yog wedged thiab AR coated.Lub Wedged Beamsplitter Phaj yog tsim los ua ntau cov ntawv theej ntawm ib qho kev tawm tswv yim.

Txhawm rau txo qis kev cuam tshuam tsis zoo (xws li, cov duab dab) tshwm sim los ntawm kev sib cuam tshuam ntawm lub teeb pom kev los ntawm sab xub ntiag thiab sab nraub qaum ntawm optic, tag nrho cov phaj beamsplitters muaj cov tshuaj tiv thaiv (AR) txheej tso rau sab nraub qaum.Cov txheej no yog tsim los rau tib lub sijhawm ua haujlwm wavelength raws li cov txheej txheem beamsplitter rau ntawm qhov chaw pem hauv ntej.Kwv yees li 4% ntawm qhov teeb meem ntawm lub teeb ntawm 45 ° ntawm lub substrate uncoated yuav tshwm sim;los ntawm kev siv AR txheej rau sab nraub qaum ntawm lub beamsplitter, qhov feem pua ntawm no raug txo kom tsawg dua 0.5% ntawm qhov tsim wavelength ntawm txheej.Ntxiv rau qhov tshwj xeeb no, sab nraub qaum ntawm tag nrho peb cov phaj puag ncig muaj 30 arcmin wedge, yog li ntawd, feem ntawm lub teeb uas tau txais kev cuam tshuam los ntawm qhov AR-coated nto yuav sib txawv.
Paralight Optics muaj phaj beamsplitters muaj ob qho tib si polarizing thiab tsis-polarizing qauv.Txheem tsis-polarizing phaj beamsplitters faib 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 phaj beamsplitters yog tsim los kho S thiab P polarization xeev txawv.

Peb cov phaj tsis-polarizingbeamsplittersyog tsim los ntawm N-BK7, Fused Silica, Calcium Fluoride thiab Zinc Selenide npog UV rau MIR wavelength ntau yam.Peb kuj muabbeamsplitters siv nrog Nd: YAG wavelengths (1064 nm thiab 532 nm).Rau qee cov ntaub ntawv ntawm cov coatings ntawm cov tsis-polarizing beamsplitters los ntawm N-BK7, thov xyuas cov duab hauv qab no los ntawm koj cov ntaub ntawv.

Tsis-Polarizing Phaj Beamsplitter

Phaj beamsplitters muaj ib tug nyias, tiaj iav phaj uas tau coated rau thawj nto ntawm substrate.Feem ntau cov phaj beamsplitters muaj cov txheej txheem tiv thaiv kev cuam tshuam ntawm qhov thib ob kom tshem tawm Fresnel tsis xav tau.Phaj beamsplitters feem ntau yog tsim los rau 45 ° AOI.Rau substrates nrog 1.5 Performance index ntawm refraction thiab 45 ° AOI, beam shift nrug (d) tuaj yeem kwv yees siv qhov sib npaug ntawm sab laug kos duab.
