Product Series Overview

Broadband Polarizing Cube Beamsplitters

The 10FC16PB.7 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 900 to 1300 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.
