Ophir Photonics Introduces BeamTrack 3A-QUAD, High Sensitivity, High Accuracy Laser Power /Energy /Position Sensor

Ophir Photonics Group, the global leader in precision laser measurement equipment, announced a BeamTrack 3A-QUAD, the first high sensitivity thermal detector to combine multiple functions – power, energy, position – in a single, compact laser sensor.

The 3A-QUAD accurately measures power from 100μWto 3Wand energy from 20μJ to 2J. In addition, the sensor accurately tracks beam position down to 0.1mm. This provides increased measurement accuracy for high sensitivity applications where it can be difficult to center laser beams on sensors with small apertures and recessed surfaces. The integrated beam position measurement function also allows tracking of beam wander as the beam drifts from its initial position.
