The 05SC16PC.21 UV Laser Line Polarizing Cube Beamsplitter provides efficient narrow-band polarization for moderate power UV lasers. Each 1/2 inch (12.7 mm) cube polarizer consists of a pair of precision right-angle prisms carefully optically contacted together to minimize wavefront distortion. The hypotenuse of one of the prisms is coated with a multilayer dielectric polarizing beamsplitter coating optimized for the 248 nm UV laser line. The four faces are antireflection coated with a multilayer dielectric coating to minimize surface reflection losses at same UV laser line. 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 100:1. These cubes are recommended for use in pulsed laser systems and for purifying polarization in multimode, high-power lasers.
