The BeamTrack series FL250A-BB-50-PPS laser measurement sensor measures laser beam size and position well as power and energy. It has a 50mm aperture and can measure beam size to 5% accuracy and position to 0.2mm accuracy. It measures power from 150mW to 250W and energy from 80mJ to 300J. It has the spectrally flat broadband coating and covers the spectral range from 0.19 to 20µm.
The sensor comes with a 1.5m cable that connects it to the electronic box, and another 0.5m cable that connects the box to a Meter or PC interface.
