Laser beam attenuator LBS-400 Series

beamsampler

Neutral Density Filter and Sampling Optic System for Pyrocams Description: The LBS-400 beam sampler attachment for Pyrocam cameras allow you to measure UV or IR wavelength laser beams with diameters up to 1 inch (25.4mm) and powers ranging from 10mW to ~500W. The beam sampler is designed so that the preferential polarization selection effect of a single wedge is cancelled out and the resulting beam image is polarization corrected to restore the polarization components of the original beam.
