Wedge material

Polarization Preserving Beam Sampler - SM1 threads, dual wedges, to 50 W*, polarization insensitive

The Polarization Preserving Beam Sampler (PPBS) uses a dual wedge design to sample a small percentage of a beam’s power for laser beam profiling applications. The PPBS samples the reflections from two orthogonal wedge windows to safely reduce the power of high intensity light while preserving the original polarization of the input beam and eliminating the effects of multiple reflections from each air-glass interface.

Wedge options:

  • BaF2: 200 nm - 11 µm
  • CaF2: 200 nm - 8 µm
  • UV-FS: 190 nm - 2200 nm
  • ZnSe: 600 nm - 16 µm


  • Clear aperture: 17.5 mm
  • Sampled percentage: 0.02%-3.75% (model and wavelength dependent)
  • Available BeamTrap for beams to 50 W
  • Available post mount kit

See charts for attentuation curves.

* requires BeamTrap, sold separately
