A Brewster window is an optic placed in the path of an optical beam at a special angle, this angle allows p-polarised light to enter and exit the window almost without any transmission losses. Any s-polarised light is reflected and this produces a fully polarised optical beam.
There are many uses for Brewster windows which include laser cavities, and ‘cleaning’ up of unpolarised light into polarised light.
Torr Scientific manufacture vacuum compatible Brewster windows from a variety of materials suited to customer requirements. We tune the angle of the window to suit the wavelength and optical material.
