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 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 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.

Non-polarizing cube beamsplitters are available for ten common laser wavelengths. They are offered in two sizes: 12.7 and 25.4 mm.

Please see Laser Line Non-Polarizing Beamsplitters for 25.4 mm diameter plate beamsplitters available.
