Polarizing Cube Beamsplitter
Polarizing Cube Beamsplitters are formed from two right angle, 45° prisms permanently cemented together. The hypotenuse is coated with an all dielectric, polarization sensitive coating designed to separate an incident, unpolarized, monochromatic beam into its S and P polarization components. The extinction ratio (Tp/Ts) exceeds 1000:1 in the transmitted beam. The two orthogonally polarized beams emerge from the cube at 90° with respect to each other. All entrance and exit surfaces are coated with a high efficiency, narrowband, anti-reflection coating.

High Power Polarizing Cube Beamsplitter
High Power Polarizing Cube Beamsplitters were specifically developed for use in high power pulsed and CW laser applications. They are formed from two right angle, 45° prisms optically contacted together. The hypotenuse is coated with an all dielectric, polarization sensitive coating designed to separate an incident, unpolarized, monochromatic beam into its S and P polarization components. The extinction ratio (Tp/Ts) exceeds 200:1 in the transmitted beam. The two orthogonally polarized beams emerge from the cube at 90° with respect to each other. All entrance and exit surfaces are coated with a high efficiency, narrowband, anti-reflection coating.

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 θB.These all dielectric coatings are highly sensitive to wavelength and angle of incidence.

IR Thin Film Plate Polarizers
IR Thin Film Plate Polarizers were developed specifically for use in high power CO2 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 100:1 in the transmitted beam. Maximum efficiency is achieved by fine angular tuning of the plate about θB. These all dielectric coatings are highly sensitive to wavelength and angle of incidence.
