The 3A-QUAD BeamTrack laser measurement sensor measures laser beam position as well as power and energy. It has a 9.5 mm aperture and can measure beam position to 0.15 mm accuracy. It measures optical power from 100 µW to 3 W and energy from 20 µJ to 2 J.
- Low power broadband absorber for 0.19-20 µm laser measurement
- 100 µW to 3 W power measurement range
- 20 µJ to 2 J energy measurement range
- Accurate tracking of beam position to fractions of a mm See All Features
Software
BeamTrack Sensors with StarLab
Support for BeamTrack sensors with Vega, Nova II, Juno, EA-1, StarLite and StarBright in StarLab application is now available. Follow step-by-step instructions to upgrade the embedded software in the BeamTrack sensor with the StarLab application
When working with other meters and interfaces it is not necessary to update the embedded software of the PE-C.
Note: BeamTrack sensors can't be upgraded via EA-1 interface.

BeamTrack Measures Power, Energy, Size and Position
Ophir BeamTrack Sensor Series, the industry's first thermal sensors that combine power and energy measurement, beam position, and beam size in a single compact device.
Sensors for Measuring Laser Power
In this short "Basics" video we review in general how one goes about measuring laser beam power, so that you'll have a clear understanding of what the different sensor types are, and when to use each type.
Beam Pointing Stability Measurement Made Easy with BeamTrack & StarLab
Do you need to align a complex optomechanical system? As you make various adjustments, Ophir’s BeamTrack sensors help you keep track of the beam’s power as well as its pointing stability, all at the same time. In this video, you’ll see how you can use BeamTrack with Ophir’s StarLab software to get a very rich and nuanced picture of your beam’s pointing stability, together with a reading of its power and current position and size - instantly.
