FL250A-BB-50-PPS

產品型號：FL250A-BB-50-PPS
產品說明：

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.

Notes: (a) The BeamTrack features are supported by Centauri, StarBright, StarLite, Nova II and Vega meters, Juno, Juno+ and EA-1 interfaces and StarLab application. Position and Size measurements work only in Power mode (but not in single shot Energy mode). (b) For powers up to 30W it is recommended to work with the fan off and then the noise level is ~3 times lower. It is also recommended to measure energy with the fan off. (c) Position accuracy for the central 20mm of the aperture as limited by beam position resolution. Position can be tracked with ±1mm accuracy over central 32mm of the aperture. Accuracy is reduced by a factor of 3 at minimum power. Position measuring center corresponds to geometrical center within <1mm. Position center can be software reset to geometric center or other desired position with Centauri, StarBright or StarLab. (d) Assumes laser beam with Gaussian (TEM00) distribution. For other modes, size measurement is relative. (e) Accuracy spec will be maintained for beams from 6 to 35mm not deviating from center more than 15% of beam diameter. (f) Calibrated for ~0.8μm, 1.064μm and 10.6μm (g) Water temperature range 18-30°C, Water temperature rate of change <1°C/min. Pressure drop across sensor 0.03MPa. (h) Position accuracy for the central 10 mm of the aperture as limited by beam position resolution. Position measuring center corresponds to geometrical center within <1mm. Position center can be software reset to geometric center or other desired position with Centauri, StarBright or StarLab.
