Polarization optics amagwiritsidwa ntchito kusintha mkhalidwe wa polarization wa zochitika ma radiation. Ma polarization optics athu amaphatikizapo polarizers, ma wave plate / retarders, depolarizers, Faraday Rotators, ndi zodzipatula zodzipatula pa UV, zowoneka, kapena IR.
Mawave plates, omwe amadziwikanso kuti retarders, amatumiza kuwala ndikusintha mawonekedwe ake popanda kufooketsa, kupotoza, kapena kusuntha mtengowo. Amachita izi mwa kuchedwetsa (kapena kuchedwetsa) chigawo chimodzi cha polarization pokhudzana ndi gawo lake la orthogonal. Mawave plate ndi chinthu chowala chomwe chili ndi nkhwangwa ziwiri zazikulu, zochedwa komanso zofulumira, zomwe zimathetsa mtengo wodulitsidwa kukhala mizati iwiri yolumikizana. Mtsinje womwe umatuluka umaphatikizananso kupanga mtengo umodzi wokhazikika. Mawave plates amatulutsa mafunde athunthu, theka ndi kotala-mafunde akuchedwa. Amadziwikanso ngati retarder kapena mbale ya retardation. Mu kuwala kopanda polarized, ma wave plates ndi ofanana ndi mazenera - onsewa ndi zigawo zalathyathyathya zomwe kuwala kumadutsamo.
⊙Quarter-wave plate: pamene kuwala kozungulira kumayikidwa pa madigiri 45 kupita kumtunda wa mbale yozungulira kotala, zomwe zimatuluka zimazungulira polarized, ndi mosemphanitsa.
⊙Mbalame ya theka-wave: Chiwiya cha theka chimazungulira kuwala kozungulira mozungulira kupita kumalo aliwonse omwe akufuna. Ngodya yozungulira imakhala yowirikiza kawiri pakati pa kuwala kowoneka ndi kuwala kozungulira.

⊙Fast Axis ndi Slow Axis: Kuwala kokhala ndi polarized motsatira nsonga yothamanga kumakumana ndi mlozera wocheperako wa refraction ndipo kumayenda mwachangu kupyola mafunde a mafunde kuposa kuwala kozungulira mozungulira pang'onopang'ono. Mzere wothamanga umasonyezedwa ndi malo ang'onoang'ono athyathyathya kapena dontho pamtunda wothamanga wa mbale yothamanga yosakwera, kapena chizindikiro pa cell mount of wave wave plate.
⊙Kuchedwetsa: Kuchedwetsa kumatanthawuza kusintha kwa gawo pakati pa chigawo cha polarization chomwe chikuwonetsedwa motsatira nsonga yothamanga ndi gawo lomwe likuyembekezeredwa motsatira pang'onopang'ono. Kuchedwerako kumatchulidwa mu magawo a madigiri, mafunde, kapena nanometers. Kuchedwetsa kumodzi kokwanira ndi kofanana ndi 360 °, kapena kuchuluka kwa ma nanometer pa utali wa chidwi. Kulekerera pakuchedwetsa nthawi zambiri kumanenedwa m'madigiri, achilengedwe kapena tizigawo ta mafunde athunthu, kapena ma nanometer. Zitsanzo za kuchedwa kwanthawi zonse ndi kulolerana ndi: λ/4 ± λ/300, λ/2 ± 0.003λ, λ/2 ± 1°, 430nm ± 2nm.
Miyezo yodziwika bwino yochedwetsa ndi λ/4, λ/2, ndi 1λ, koma mfundo zina zitha kukhala zothandiza pamapulogalamu ena. Mwachitsanzo, kulingalira kwamkati kuchokera ku prism kumayambitsa kusintha kwa gawo pakati pa zigawo zomwe zingakhale zovuta; wolipirira waveplate akhoza kubwezeretsa polarization ankafuna.
⊙Dongosolo Lambiri: M'magawo angapo opangira ma wave, kuchedwetsa kwathunthu ndikuchedwetsa komwe kumafunikira kuphatikiza nambala yonse. Gawo lachiwerengero chowonjezereka liribe mphamvu pa ntchitoyo, mofanana ndi momwe wotchi yowonetsera masana lero ikuwoneka mofanana ndi yomwe ikuwonetsa masana pa sabata - ngakhale kuti nthawi yawonjezedwa, ikuwonekabe chimodzimodzi. Ngakhale ma waveplates angapo amapangidwa ndi chinthu chimodzi chokha, amatha kukhala okhuthala, omwe amathandizira kagwiridwe kake ndi kuphatikiza dongosolo. Kukula kwakukulu, komabe, kumapangitsa kuti ma waveplates angapo azitha kusinthika pang'onopang'ono chifukwa cha kusintha kwa mawonekedwe a wavelength kapena kusintha kwa kutentha kozungulira.
⊙Zero Order: Ziro order wave plate idapangidwa kuti izipangitsa kuti mafunde athunthu azizero osapitilira, kuphatikiza gawo lomwe mukufuna. Mwachitsanzo, mbale za Zero Order Quartz Wave zimakhala ndi ma waveplates awiri amtundu wa quartz omwe ali ndi nkhwangwa zawoloka kuti kubwezeredwa bwino ndiko kusiyana pakati pawo. Mbali yodziwika bwino ya zero order wave plate, yomwe imadziwikanso kuti compound zero order wave plate, imakhala ndi ma wave plate angapo a zinthu zomwezo zomwe zayikidwa kuti zigwirizane ndi optical axis. Masanjidwe angapo a ma wave plates amatsutsana ndi kuchedwetsa kusinthika komwe kumachitika m'magawo amtundu uliwonse, kumapangitsa kukhazikika kwa kuchedwa kwa kusintha kwa mafunde ndi kusintha kwa kutentha kozungulira. Mawave amtundu wa ziro oyitanitsa siziwongolerera kusintha kochedwa komwe kumachitika chifukwa cha zochitika zina. Chowonadi cha zero order wave plate chimapangidwa ndi chinthu chimodzi chokhacho chomwe chasinthidwa kukhala mbale yowonda kwambiri yomwe ingakhale yokhuthala pang'ono kuti ikwaniritse gawo linalake la kuchedwa paziro. Ngakhale kuonda kwa mbaleyo kungapangitse kunyamula kapena kuyika ma waveplate kukhala ovuta kwambiri, ma waveplate enieni a zero amapereka kukhazikika kwapamwamba kwa kutsetsereka kwa mafunde, kusintha kwa kutentha kozungulira, ndi mbali yosiyana ya zochitika kuposa ma waveplates ena. Ma mbale a Zero Order Wave amawonetsa magwiridwe antchito bwino kuposa ma mbale angapo oyitanitsa. Amawonetsa bandwidth yotakata komanso kukhudzika kochepa kwa kutentha ndi kusintha kwa kutalika kwa mawonekedwe ndipo ziyenera kuganiziridwa ngati ntchito zovuta kwambiri.
⊙Achromatic: Mafunde achromatic amakhala ndi zida ziwiri zosiyana zomwe zimachotsa kubalalitsidwa kwa chromatic. Magalasi amtundu wa achromatic amapangidwa kuchokera ku mitundu iwiri ya magalasi, omwe amafananizidwa kuti akwaniritse utali wofunikira pomwe akuchepetsa kapena kuchotsa chromatic aberration. Achromatic waveplates amagwira ntchito pa mfundo yomweyo. Mwachitsanzo, ma Achromatic Waveplates amapangidwa kuchokera ku crystal quartz ndi magnesium fluoride kuti akwaniritse kuchedwa kosalekeza kudutsa gulu lalikulu lowonera.
⊙Super Achromatic: Ma waveplate apamwamba kwambiri achromatic ndi mtundu wapadera wa ma waveplate achromatic omwe amagwiritsidwa ntchito kuthetsa kufalikira kwa chromatic kwa ma waveband ambiri. Ma waveplates ambiri apamwamba kwambiri amatha kugwiritsidwa ntchito pazowoneka bwino komanso dera la NIR lomwe lili pafupi ndi zofanana, ngati si zabwinoko, zofananira kuposa ma wave achromatic wave. Kumene ma waveplates amtundu wa achromatic amapangidwa ndi quartz ndi magnesium fluoride ya makulidwe ake, ma waveplates apamwamba kwambiri amagwiritsa ntchito gawo la safiro lowonjezera limodzi ndi quartz ndi magnesium fluoride. Kukula kwa magawo atatu onsewa kumatsimikiziridwa mwanzeru kuti athetse kufalikira kwa chromatic kwa utali wautali wa mafunde.
