UV Cube Beamsplitter, Non-Polarizing, 25.4 mm, 355 nm Laser Line
The 10SC16NP.43 Non-Polarizing Cube Beamsplitter is a 1.0 inch (25.4 mm) UV fused silica cube optimized for 355 nm. Our UV non-polarizing cube beamsplitters provide 50/50 beam splitting with little alteration to the beam polarization for use with HeCd lasers, nitrogen lasers, Nd:YAG lasers, and mercury arc lamps. It is constructed from a pair of UV fused silica precision right-angle prisms. Specifications
