Cube dielectric polarizers consist of two cemented right angle prisms with dielectric multilayer coating inside. The polarizer transmission for the „P” component is very high, but „S” component is reflected. Dielectric layers are always made of materials with such refraction indexes so as to obtain incidence at Brewster angle. Right angle prisms are made of flint glass. Since they are cemented, this kind of polarizers can be used only at lower power densities, but they can operate in a broad range of wavelengths. We. produce dielectric cube polarizers for the visible range and near infrared.
