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.
