Product documentation

Description

Designed for broadband applications, broadband polarizing cube beamsplitter offers 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. 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.
