Our laser line non-polarizing cube beamsplitters are insensitive to the polarization of an incoming beam. They provide true 50/50 beamsplitting without altering the beam polarization. Incoming beams are both transmitted and reflected at 50%, with the s and p-polarized components matched to within 3%.

Unlike the metal-dielectric hybrid broadband non-polarizing cube beamsplitters, these all-dielectric coatings exhibit nearly zero absorption resulting in the true 50/50 split of the beam. Low absorption also means these beamsplitters have a higher damage threshold.

These beamsplitters consist of a pair of precision right-angle prisms made with BK7 or UV fused silica, are carefully cemented together to minimize wavefront distortion. The hypotenuse of one of the prisms is coated with a multilayer all-dielectric non-polarizing beamsplitter coating optimized for specific laser lines. The four faces are antireflection coated with a multilayer dielectric coating to minimize surface reflection losses at the laser lines.

Newports' non-polarizing cube beamsplitters are available for eleven common laser wavelengths and are offered in 12.7 and 25.4 mm sizes.

Please see Plate Beamsplitters for 25.4 mm diameter plate beamsplitters.
