High Energy Polarizing Cube Beamsplitters are made of UV FS and optimized to be used for wavelength of 355, 532, 800, 1064 nm or wavelength ranges of 420-680 nm and 700-1080 nm.
Cube beamsplitters are optically contacted and feature laser damage thershold up to 15 J/cm2. All four outer faces of the cube beamsplitters have anti-reflection coating. High Energy Polarizing Cubes are provided unmounted or conveniently mounted on M2Ps mount.
