Premium performance, high power separation of s- and p-polarization at Nd:YAG laser wavelengths. Designed for premium performance, high power separation of s- and p-polarization, these ion beam sputtered cube beamsplitters deliver excellent transmission of p-polarized light with extinction ratios of up to >1000:1. They are available from stock at Nd:YAG wavelengths from 266 – 1064 nm. Other wavelengths are available upon request.

Ion Beam Sputtered High Energy Laser Line Polarizing Cube Beamsplitters combine some of the best technologies we have to offer to deliver premium performance under high power operating conditions.  Ion beam sputtered coatings are deposited on precisely fabricated UV-grade fused silica prisms, which are then mated using our patent-pending, epoxy-free Chemically Active Direct Bonding® technology to achieve zero-bondline thickness.  These beamsplitters separate light based on polarization, reflecting s-polarized light and transmitting p-polarized light with high efficiency at a specific laser wavelength.
