Beamsplitters nthawi zambiri amagawidwa molingana ndi kapangidwe kake: kyubu kapena mbale. Plate beamsplitter ndi mtundu wodziwika bwino wa beamsplitter womwe umapangidwa ndi gawo lapansi lagalasi lopyapyala lokhala ndi zokutira zowoneka bwino zokongoletsedwa ndi 45° angle of incident (AOI). Standard plate beamsplitters amagawanitsa kuwala kwa zochitika ndi chiŵerengero chodziwika chomwe sichidalira kutalika kwa kuwala kapena dziko la polarization, pamene polarizing plate beamsplitters amapangidwa kuti azisamalira mayiko a S ndi P mosiyanasiyana.
Ubwino wa beamsplitter ya mbale ndiwotsika pang'ono, kuyamwa pang'ono chifukwa cha magalasi ochepa, mapangidwe ang'onoang'ono komanso opepuka poyerekeza ndi beamsplitter ya cube. Kuipa kwa mbale beamsplitter ndi zithunzi mzukwa amapangidwa ndi kuwala zimaonekera mbali zonse za galasi, kusamutsidwa ofananira nawo wa mtengo chifukwa cha makulidwe a galasi, kuvutika phiri popanda mapindikidwe, ndi tilinazo polarized kuwala.
Miyendo yathu ya mbale imakhala ndi malo ophimbidwa kutsogolo omwe amatsimikizira chiŵerengero chogawanika cha mtengo pamene kumbuyo kuli kopiringizidwa ndi AR yokutidwa. The Wedged Beamsplitter Plate idapangidwa kuti ipange makope angapo osasunthika a mtengo umodzi wolowetsa.
Pofuna kuchepetsa kusokoneza kwapathengo (mwachitsanzo, zithunzi za mizimu) zomwe zimadza chifukwa cha kuyanjana kwa kuwala komwe kumawonekera kuchokera kutsogolo ndi kumbuyo kwa optic, zonsezi zimakhala ndi antireflection (AR) zokutira zomwe zimayikidwa kumbuyo. Chophimba ichi chapangidwa kuti chikhale chofanana ndi kutalika kwake kogwira ntchito ngati zokutira za beamsplitter kutsogolo. Pafupifupi 4% ya zochitika zowala pa 45 ° pagawo losatsekedwa zidzawonetsedwa; poyika zokutira za AR kuseri kwa beamsplitter, gawoli limachepetsedwa mpaka pafupifupi 0.5% pamapangidwe a kutalika kwa zokutira. Kuphatikiza pa izi, kumbuyo kwa mizati yathu yonse yozungulira imakhala ndi 30 arcmin wedge, chifukwa chake, kagawo kakang'ono ka kuwala komwe kamawonekera kuchokera pamalo okutidwa ndi AR kudzasiyana.
Paralight Optics imapereka ma plate beamsplitters omwe amapezeka polarizing komanso osapanga polarizing. Miyendo yokhazikika yopanda polarizing imagawanitsa kuwala kwa zochitika ndi chiŵerengero chodziwika chomwe sichidalira kutalika kwa mafunde kapena polarization state, pamene polarizing plate beamsplitters adapangidwa kuti azisamalira mayiko a S ndi P mosiyanasiyana.
mbale yathu yopanda polarizingbeamsplittersamapangidwa ndi N-BK7, Fused Silica, Calcium Fluoride ndi Zinc Selenide yophimba UV mpaka MIR wavelength range. Timaperekansoma beamsplitters ogwiritsidwa ntchito ndi Nd: YAG wavelengths (1064 nm ndi 532 nm). Kuti mumve zambiri za zokutira za mizati yopanda polarizing yolembedwa ndi N-BK7, chonde onani ma graph otsatirawa kuchokera pamawu anu.
