General Optics
Brewster Windows
Obtain polarized laser output or achieve lossless transmission of p-polarized light using these plane parallel windows, designed for operation at Brewster's angle.
These uncoated ZnSe windows will transmit 100% at 10.6 µm when used at 67.4º angle of incidence. S-polarized light will be reflected 50% per surface at this angle of incidence.
Brewster Windows Selection
Choose from our standard range of ZnSe windows or specify exactly the component you require. Ge Brewster windows are available for use at 76.0º angle of incidence.
