The FL250A-BB-50-PPS BeamTrack laser measurement sensor measures laser beam size and position as well as power and energy. It has a 50 mm aperture and can measure beam size to 5% accuracy and position to 0.3 mm + 7% of distance from center accuracy. It measures power from 150 mW to 250 W and energy from 80 mJ to 300 J. It has the spectrally flat broadband coating and covers the spectral range from 0.19 to 20 µm.
- Broadband absorber for 0.19-20 µm laser measurement
- 150 mW to 250 W continuous power measurement range
- 80 mJ to 300 J energy measurement range
- Accurately tracks laser beam position to fractions of a mm
- Monitors the size of a laser beam 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.
Features
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.
How to Measure Power of Broadband Sources
This video explains how to use Ophir sensors and meters to measure the power or energy of broadband light sources such as solar radiation, flash lamps, LEDs, etc.
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.
