Medium - High Power BeamTrack-Power / Position / Size Sensors
150mW to 1000W
Features
• All the features of standard power sensors plus...
• Accurate tracking of beam position to fractions of a mm
• Monitoring of the laser beam size
Description:
The BeamTrack series 1000W-BB-34-QUAD laser measurement sensor measures laser beam position well as power and energy. It has a 34mm aperture and can measure beam position to 0.5mm accuracy. It measures power from 5W to 1000W and energy from 500mJ 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.

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.
Notes: (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.
Notes: (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.
Notes: (d) Assumes laser beam with Gaussian (TEM00) distribution. For other modes, size measurement is relative.
Notes: (e) Accuracy spec will be maintained for beams from 6 to 35mm not deviating from center more than 15% of beam diameter.
Notes: (f) Calibrated for ~0.8µm, 1.064µm and 10.6µm
Notes: (g) Water temperature range 18-30°C, Water temperature rate of change <1°C/min. Pressure drop across sensor 0.03MPa.
Notes: (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.
