TECHSPEC® Brewster Windows are designed to present a circular profile when oriented at Brewster’s angle (55.57°). TECHSPEC® Brewster Windows feature laser grade surface quality and parallelism, in addition to limiting transmitted wavefront distortion to λ/10. When used at 55.57°, these windows minimize the loss of P-polarized light, ideal for use within laser cavities and for producing linearly polarized light.
