Data Sheet
Brewster Windows are primarily used in laser cavities to produce a beam with a high degree of polarization purity. When unpolarized light is incident on an uncoated substrate at Brewster’s Angle, the reflected portion is completely S polarized and the transmitted portion is partially P polarized. Multiple passes through the ...

Data Sheet
Brewster Windows are windows designed for use at Brewster\'s angle (usually uncoated). This is the angle where only incident p-polarized light has 0% transmission loss. They are an economical option for coupling linearly polarized light into sealed optical systems and to select the polarization of light traveling in optical cavities. ...

Did You know?

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.
