The BeamTrack series 3A-P-QUAD laser measurement sensor measures laser beam position well as power and energy. It has a 12mm aperture and can measure beam position to 0.15mm accuracy. It measures power from 160µW to 3W and energy from 30µJ to 2J. It has the P type volume absorber that covers the spectral range from 0.15 to 8µm.
