Features
High energy applications | 1000:1 @ narrow band | 500:1 @broadband

CRYLIGHT developed high power polarization beamsplitter cubes which are specially designed for application in high power lasers. The polarizing beamsplitter cubes split polarized beams into two polarized beams, S-polarized light is reflected at a 90deg. P-polarized light is transmitted.  A dielectric coating is always on the hypotenuse. These cubes are deep-optically contacted and have higher damage threshold than that of cemented cubes.
