High Power Thin Film Plate Polarizers
High Power Thin Film Plate Polarizers
were developed specifically for use in high power pulsed and CW laser
applications. Designed to operate at Brewster¡¯s Angle, they separate
an incident, unpolarized, monochromatic beam into its S and P polarization
components. The extinction ratio (TP/TS) exceeds 200:1 (for λ
> 400) nm and 100:1 (for λ
< 400 nm) in the transmitted beam. Maximum efficiency is achieved by
fine angular tuning of the plate about 0B.These all
dielectric coatings are highly sensitive to wavelength and angle of
incidence.
