Brewster Window, Minor: 12.5 mm, Major: 22.11 mm, 2.0 mm thick

The BQW-1 Brewster Window is made with UV grade fused silica with laser grade surface quality and parallelism to make it the ideal polarizer to use within a laser cavity. The BQW-1 has a 22.11 mm major axis, a 12.5 mm minor axis, and is 2.0 mm thick. When oriented at the 55.57° Brewster's angle, this window is designed to generate circular profile, allowing P-Polarized light to pass through the window with minimum losses while the S-Polarized light being reflected off the Brewster window. This window limits the transmitted wavefront distortion to 1/10 of wave.
