Tech Spec high-energy polarizing cube beamsplitters handle laser-power densities up to 5 J/cm² and use multilayer dielectric film technology to minimize reflection and absorption losses. They offer extinction ratio of greater than 500:1. Precision-fused silica substrate and optical contact bonding prevents need for adhesive between prisms and improves parallelism of incoming and exiting beams. V-coat AR coating at design wavelength eliminates energy loss.
