Polarizing Beamsplitter Cubes
Split high-power laser beams by polarization using these efficient cube beamsplitters with extinction ratios >1000:1, which do not produce offset ghost beams.
These cube beamsplitters are assembled from two right-angle prisms, with a high-efficiency, all-dielectric polarization coating on the hypotenuse of one. They are ideal for use with pulsed and other high-power lasers, and for telecom applications.
