The LBS-400 beam sampler attachment for Pyrocam cameras (P/N SP90349) allows you to measure 193 to 355 nm wavelength laser beams with diameters up to 1 inch (25.4mm) and powers ranging from 10 mW to ~500W⁽¹⁾. The CaF₂ beam sampler is designed so that the preferential polarization selection effect of a single wedge is canceled out and the resulting beam image is polarization corrected to restore the polarization components of the original beam.

⁽¹⁾ For Gaussian beam diameter <1/2 the clear aperture and depending on ND filter and camera saturation limits the maximum power may be as high as 1200W.
