Cube Beamsplitter, Polarizing, 25.4 mm, 830 nm Laser Line

Laser Line Polarizing Cube Beamsplitters

The 10BC16PC.7 Laser Line Polarizing Cube Beamsplitter provides efficient narrowband polarization for higher power lasers. This polarizer consists of a pair of precision 1 inch (25.4 mm) 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 the 830 nm laser line. 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 1000:1. This cube is recommended for use in pulsed laser systems and for purifying polarization in multimode, high-power lasers.
