Medium Power BeamTrack-Power / Position / Size Sensors
Description:
The BeamTrack series 50(150)A-BB-26-QUAD laser measurement sensor measures laser beam position as well as power and energy. It has a 26mm aperture and can measure position to 0.1mm accuracy. It measures power from 40mW to 50W continuously and to 150W intermittently.It can measure energy from 20mJ to 100J.
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.
40mW to 150W
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

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 10mm of the aperture as limited by beam position resolution. Position can be tracked with ±1mm accuracy over the entire 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 3.5 to 17mm not deviating from center more than 15% of beam diameter. For beams below 8mm in size and powers above 75W error in size can reach ±10%.
