Ophir Photonics announced the BeamTrack 3A-QUAD, a high-sensitivity thermal laser sensor. The 3A-QUAD accurately measures power from 100 µW to 3W, and energy from 20 µJ 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.
The 3A-QUAD has a small 9.5mm aperture and measures a broad spectral range, from 190nm to 20 µm. BeamTrack sensors divide the sensor signal into quadrants, measuring and comparing the output to determine the position of the center of the beam to a high degree of accuracy. This quantitative measure of beam position provides the ability to track beam wander.
The sensor operates with Ophir’s Nova II and Vega smart displays, and Juno PC interface. Each display features a “Smart Connector” interface that automatically configures and calibrates the display when plugged into one of the company’s measurement heads.
