Ophir Photonics (North Logan, UT) has announced the newest member of the BeamTrack family, the FL250A-BB-50-PPS. BeamTrack is a unique series of thermal detectors that combine multiple functions in one device: laser power, energy, beam position, and beam size. The sensors also provide information on beam centering and wander, all in a compact unit the size of a single function sensor of the same power level. The first BeamTrack detectors – measuring 3W, 10W, 50W, and 150W – were introduced in 2012.
The FL250A-BB-50-PPS measures laser power from 150mW to 250W, and energy from 80mJ to 300J. Beam position is accurate to 0.2 mm. A patented beam size detector embedded in the sensor is accurate to ±5% for a Gaussian beam. Sensors are available with a range of aperture sizes, from 12mm to 50mm. The broadband absorbers of the detectors can measure a spectral range from 150nm to 20μm.
