Polarizing Cube Beamsplitter, High Energy Nd:YAG, 12.7 mm, 266 nm

High Energy Laser Line Polarizing Cube Beamsplitters

The 05BC15PH.2 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 266 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 12.7 x 12.7 x 12.7 mm and can be conveniently mounted on Newport holders.
