Edmund Optics Inc. Polarizing Cube Beamsplitter 20mm NIR NT49-871

Visible and NIR Coating Options Offered 500:1 Extinction Ratio AR Coated for <0.5% Reflection per Surface Designed for broadband applications, TECHSPEC® Broadband Polarizing Cube Beamsplitters offer a transmission of greater than 90% for P-polarized light and a reflection efficiency of greater than 99% for S-Polarized light across the entire design wavelength range. Each beamsplitter consists of a pair of precision high tolerance right angle prisms cemented together with a dielectric coating on the hypotenuse of one of the prisms. An anti-reflection (AR) coating has been applied to each face of the beamsplitter to achieve less than 0.5% reflection per surface.
