Polarizing Cube Beamsplitters

Beamsplitters amachita ndendende zomwe dzina lawo limatanthawuza, kugawa mtengo pamlingo womwe wasankhidwa mbali ziwiri.Ma beamsplitters okhazikika amagwiritsidwa ntchito ndi kuwala kopanda polarized monga zachilengedwe kapena polychromatic, amagawa mtengowo ndi kuchuluka kwa mphamvu, monga 50% transmission and 50% reflection, kapena 30% transmission and 70% reflection.Ma dichroic beamsplitters amagawanitsa kuwala kobwerako ndi kutalika kwa mawonekedwe ndipo amagwiritsidwa ntchito popanga fulorosenti kuti alekanitse njira zachisangalalo ndi zotulutsa, ma beamsplitters awa amapereka chiŵerengero chogawanika chomwe chimadalira kutalika kwa kuwala kwa chochitikacho ndipo n'chothandiza pophatikiza / kugawa matabwa a laser osiyanasiyana. mitundu.

Beamsplitters nthawi zambiri amagawidwa molingana ndi kapangidwe kake: kyubu kapena mbale.Ma cube beamsplitters amapangidwa ndi ma prism awiri akumanja omwe amalumikizidwa palimodzi pa hypotenuse ndi zokutira zowunikira pang'ono pakati.Malo a hypotenuse a prism imodzi amakutidwa, ndipo ma prism awiriwo amalumikizidwa palimodzi kuti apange mawonekedwe a cubic.Pofuna kupeŵa kuwononga simenti, tikulimbikitsidwa kuti kuwalako kulowetsedwe ku prism yokutidwa, yomwe nthawi zambiri imakhala ndi chizindikiro pansi.
Ubwino wa ma cube beamsplitters amaphatikiza kuyika kosavuta, kukhazikika kwa zokutira zowoneka bwino chifukwa zili pakati pazigawo ziwiri, ndipo palibe zithunzi za mizukwa popeza zowunikira zimabwerera komwe kumachokera.Kuipa kwa kyubu ndikuti ndi yayikulu komanso yolemera kuposa mitundu ina ya ma beamsplitters ndipo simabisala motalikirapo ngati ma pellicle kapena madontho a polka.Ngakhale timapereka njira zambiri zokutira zosiyanasiyana.Komanso ma cube beamsplitters amayenera kugwiritsidwa ntchito ndi matabwa opindika chifukwa kusinthasintha kapena kupatukana kumathandizira kuti chithunzithunzi chiwonongeke kwambiri.

Paralight Optics imapereka ma cube beamsplitters omwe amapezeka polarizing komanso osapanga polarizing.Miyendo yopanda polarizing cube beamsplitters idapangidwa kuti igawanitse kuwala kwa chochitika ndi chiŵerengero chodziwika chomwe sichidalira kutalika kwa mawonekedwe a kuwala kapena polarization state.Pomwe ma polarizing beamsplitters amatumiza kuwala kwa P polarized ndikuwonetsa kuwala kwa S polarized komwe kumalola wogwiritsa ntchito kuwonjezera kuwala kwa polarized mu optical system, atha kugwiritsidwa ntchito kugawa kuwala kopanda polarized pamlingo wa 50/50, kapena kugwiritsa ntchito kulekanitsa polarization monga kudzipatula kwa kuwala.

Polarizing Cube Beamsplitter

Zindikirani: The extinction ratio (ER) imatanthauzidwa ngati chiŵerengero cha kuwala kwa p-polarized kuwala kwa s-polarized, kapena Tp/Ts.Komabe, ndikofunikira kuzindikira kuti Tp/Ts nthawi zambiri silingana ndi chiyerekezo cha kuwala kwa s-polarized kuwala kwa p-polarized, kapena Rs/Rp.Kunena zoona chiŵerengero cha Tp/Ts (ER) chimakhala chabwinoko kuposa chiŵerengero cha Rs/Rp.Izi zili choncho chifukwa ma beamsplitters nthawi zambiri amagwira ntchito powonetsa s-polarization koma sagwira ntchito poletsa p-polarization kuti isawonekere, mwachitsanzo, kuwala kopatsirana kumakhala kopanda s-polarization, koma kuwala kowunikira sikuli kopanda p-polarization.
