I-Glan Laser prism polarizer yenziwe ngamaprism amabili afanayo ane-birefringent ahlanganiswe nendawo yomoya.I-polarizer iwukuguqulwa kohlobo lwe-Glan Taylor futhi idizayinelwe ukuba ibe nokulahlekelwa kokubonakala okuncane endaweni yokuhlangana kweprism.I-polarizer enamafasitela amabili okuphuma ivumela i-beam enqatshiwe ukuba iphume ku-polarizer, okwenza kufiseleke kakhulu kumalaser wamandla aphezulu.Izinga eliphezulu lalobu buso liphansi kakhulu uma liqhathaniswa nobuso bokungena nokuphuma.Akukho ukucaciswa kwekhwalithi yendawo yokumba eklwejwayo eyabelwe lobu buso.
