PBS/NPBS
PBS/NPBS
PBS prisms split unpolarized light into transmitted p-polarized and reflected s-polarized beams via dielectric coatings at Brewster angles. They achieve >1000:1 extinction ratios and >90% transmission for p-light, ideal for polarization-sensitive systems like interferometers and projectors (420–1600 nm)
NPBS prisms maintain near-identical splitting ratios (50:50) for all polarization states, with |Tp-Ts| <8% and minimal polarization-dependent loss. Designed for polarization-insensitive applications in imaging/LIDAR (400–1600 nm)
