Polarizer kapena yomwe imadziwikanso kuti wave plate kapena retarder ndi chipangizo chowunikira chomwe chimasintha polarization state ya mafunde owala akudutsamo.
Mawaveplates awiri odziwika bwino ndi theka-waveplates, omwe amasintha momwe amayendera polarized polarized light, ndi quarter-waveplates, omwe amasintha kuwala kozungulira kukhala kuwala kozungulira mozungulira komanso mosinthanitsa.Magawo a Quarter wave angagwiritsidwenso ntchito kupanga elliptical polarization.
Ma polarizers, kapena ma waveplates momwe amatchulidwiranso, amapangidwa ndi zida za birefringent (monga quartz) zomwe zimakhala ndi zizindikiro zosiyana zowunikira kuwala kozungulira mozungulira limodzi kapena lina la nkhwangwa ziwiri za perpendicular crystallographic.
Zinthu zopangira polarizing zimagwiritsidwa ntchito pojambula zithunzi kuti muchepetse glare kapena malo otentha, kuwonjezera kusiyanitsa, kapena kuyesa kupsinjika.Polarization itha kugwiritsidwanso ntchito kuyeza kusintha kwa maginito, kutentha, kapangidwe ka maselo, kulumikizana kwamankhwala kapena kugwedezeka kwamawu.Polarizers amagwiritsidwa ntchito kufalitsa dziko linalake polarization pamene kutsekereza ena onse.Kuwala kwa polarized kumatha kukhala ndi mzere, wozungulira kapena elliptical polarization.
Khalidwe la ma waveplates (mwachitsanzo, mbale za theka, mbale za kotala, ndi zina zotero) zimadalira makulidwe a kristalo, kutalika kwa kuwala ndi kusintha kwa refractive index.Posankha moyenera mgwirizano pakati pa magawowa, kusintha kwa gawo loyendetsedwa kungayambitsidwe pakati pa zigawo ziwiri za polarization za kuwala kwa kuwala, potero kusintha polarization yake.
Ma polarizer amakanema owoneka bwino amapangidwa pogwiritsa ntchito ukadaulo wapamwamba kwambiri wamakanema opaka nthunzi kuti agwire bwino ntchito.Ma polarizers amapezeka ndi zokutira polarizing mbali zonse za polarizer, kapena ndi polarizing zokutira pa mbali yolowera ndi apamwamba multilayer anti-reflection zokutira pa zotuluka mbali.
