Window ɗin Brewster wasu sinadarai ne marasa rufi waɗanda za a iya amfani da su a jeri azaman polarizers, ko don tsabtace katako mai ɗanɗano.Lokacin da aka sanya shi a kusurwar Brewster, ɓangaren P-polarized na hasken yana shiga ya fita daga taga ba tare da hasarar tunani ba, yayin da ɓangaren S-polarized yana nuna wani bangare.Ingancin 20-10 na karce-tona da λ/10 da aka watsar da kuskuren gaban gaban windows ɗin mu na Brewster ya sa su zama kyakkyawan zaɓi don cavities na Laser.

Window Brewster yawanci ana amfani dashi azaman polarizers a cikin cavities na Laser.Lokacin da aka sanya shi a kusurwar Brewster (55° 32′ a 633 nm), ɓangaren P-polarized na hasken zai wuce ta taga ba tare da asara ba, yayin da wani yanki na ɓangaren S-polarized za a nuna a gefen tagar Brewster.Lokacin da aka yi amfani da shi a cikin rami na Laser, taga Brewster da gaske yana aiki azaman polarizer.
