An angle of incidence at which light with a particular polarization is perfectly transmitted through a transparent dielectric surface, with no reflection, is called Brewster’s angle after the Scottish physicist David Brewster. Brewster windows are uncoated substrates which can be used as polarizers. When positioned at Brewster's Angle, the P-polarized component of light enters and exits the window without reflection losses, while the S-polarized component is reflected. Brewster windows are often fabricated using UV fused silica that does not have laser-induced fluorescence, which makes it well-suited for applications that use ultraviolet to near infrared light. They are used in laser physics, holography, polarization optics and more.
