Cube Beamsplitter, Polarizing, 25.4 mm, 1200-1600 nm

1.0 inch (25.4 mm) broadband polarizing cube beamsplitter

The 10FC16PB.9 Broadband Polarizing Cube Beamsplitter provides efficient polarization for use with multiple or tunable sources. The 25.4 mm cube polarizer consists of a pair of precision right-angle prisms carefully cemented together to minimize wavefront distortion. The hypotenuse of one of the prisms is coated with a multilayer dielectric polarizing beamsplitter coating optimized for a 1200 to 1600 nm wavelength range. The four faces are antireflection coated with a multilayer dielectric coating to minimize surface reflection losses.
An unpolarized beam is split into two orthogonal, linearly polarized components. P-polarized light is transmitted, while s-polarized light is reflected, both with negligible absorption. The extinction ratio is better than 500:1, yet it averages 1000:1. This unique component provides all the benefits of a broadband polarizer in a standard cube configuration.
