The 10BC15PH.4 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 355 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 25.4 x 25.4 x 25.4 mm and can be conveniently mounted on Newport holders.
