BeamTrack 3A-QUAD

Ophir Photonics has announced its BeamTrack 3A-QUAD, a high sensitivity thermal detector that combines multiple functions, power, energy and position in a single, compact sensor.

The 3A-QUAD accurately measures power from 100µW to 3W and 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 centre laser beams on sensors with small apertures and recessed surfaces.

The 3A-QUAD has a small 9.5mm aperture and measures a broad spectral range from 190nm to 20µm. The integrated beam position measurement function also allows tracking of beam wander as the beam drifts from its initial position.
