High Precision Optical Brewster Windows
Brewster Windows are uncoated substrates which designed to present a circular profile when oriented at Brewster’s angle (55.57°). Brewster windows are manufactured from UV fused silica, which exhibits virtually no laser-induced fluorescence. These windows minimize the loss of P-polarized light, ideal for use within laser cavities and for producing linearly polarized light.
