The 05BC15PH.10 High-energy Polarizing Cube Beamsplitter provides efficient narrowband polarization for use with Nd:YAG lasers. Each polarizer consists of a pair of precision right-angle prisms optically contacted together. No cement is used. Optimized for 1550 nm, a damage threshold of up to 5 J/cm2 with 10 ns pulse at 266 nm is achievable. This high-energy polarizing cube beamsplitter is 5.0 x 5.0 x 5.0 mm and can be conveniently mounted on Newport holders.
