Standard specifications

4Lasers standard high contrast Brewster-type and 45° thin-film polarizers provide a high extinction ratio Tp:Ts > 1000:1 thanks to the ion beam sputtered (IBS) thin-film coatings. Moreover, these polarizers are ideal for high-power levels and UV wavelength range. 4Lasers design and manufacture standard and custom Brewster type high contrast polarizers for the wavelength range between 230 nm and 2000 nm with face dimensions up to 160 mm.
