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.
