EKSMA Optics Thin Film Laser Polarizers

Thin film polarizers separate or combine the s- and p-polarization components at 45° angle of incidence. They are designed for use in high energy lasers. Polarizers are made from UV FS and feature high laser damage threshold reaching 10 J/cm2 at 1064 nm.
We offer round standard and high extinction ratio (Tp:Ts:>1000:1) polarizers working at 45° angle of incidence.
