Rochon Polarizer
Rochon Prisms faib cov kab hluav taws xob polarized arbitrarily input beam rau hauv ob qho tib si polarized output beams.Cov kab hluav taws xob zoo tib yam tseem nyob ntawm tib qhov chaw kho qhov muag raws li cov kab hluav taws xob nkag, thaum lub teeb hluav taws xob txawv txav los ntawm lub kaum sab xis, uas nyob ntawm lub wavelength ntawm lub teeb thiab cov khoom ntawm lub prism (saib Beam Deviation graphs nyob rau hauv lub rooj rau sab xis) .Cov kab hluav taws xob tso zis muaj qhov sib npaug siab polarization extinction ntawm> 10 000: 1 rau MgF2 prism thiab> 100 000: 1 rau a-BBO prism.

Achromatic Depolarizers
Cov achromatic depolarizers no muaj ob lub pob zeb siv lead ua quartz, ib qho yog ob zaug tuab li lwm qhov, uas yog sib cais los ntawm ib lub nplhaib hlau nyias.Lub rooj sib txoos yog tuav ua ke los ntawm epoxy uas tau siv rau ntawm ntug sab nraud (piv txwv li, qhov tseeb aperture yog dawb los ntawm epoxy), uas ua rau lub optic muaj kev puas tsuaj loj.

Polarizer Rotators
Polarization roators muab 45 ° mus rau 90 ° kev sib hloov ntawm ib tug xov tooj ntawm ntau laser wavelengths.Qhov kho qhov muag axis nyob rau hauv apolarization rotator yog perpendicular mus rau lub ntsej muag polished.Qhov tshwm sim yog hais tias lub orientation ntawm muab linearly polarized lub teeb yog tig raws li nws propagates los ntawm lub ntaus ntawv. .

Fresnel Rhomb Retarders
Fresnel Rhomb Retarders zoo li broadband waveplates muab cov qauv λ / 4 lossis λ / 2 retardance tshaj qhov dav ntawm wavelengths ntau dua li qhov ua tau nrog birefringent waveplates.Lawv tuaj yeem hloov daim hlau retardation rau broadband, ntau kab lossis tunable laser qhov chaw.
