NEWPORT 优铂特 05BC15PH.4 高能量 Nd:YAG 偏光立方体分光镜
偏振立方体分束器，高能量 Nd:YAG，12.7 mm，355 nm
概览
The 05BC15PH.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 12.7 x 12.7 x 12.7 mm and can be conveniently mounted on Newport holders.
