FL250A-BB-50-PPS
The BeamTrack series FL250A-BB-50-PPS laser measurement sensor measures laser beam size and position well as power and energy. It has a 50mm aperture and can measure beam size to 5% accuracy and position to 0.2mm accuracy. It measures power from 150mW to 250W and energy from 80mJ to 300J. It has the spectrally flat broadband coating and covers the spectral range from 0.19 to 20µm.
The sensor comes with a 1.5m cable that connects it to the electronic box, and another 0.5m cable that connects the box to a Meter or PC interface.

FAQ
Can I measure position and size of a pulsed laser using a BeamTrack sensor?
When using a BeamTrack sensor with StarLab on a PC, can I have StarLab log Position and Size data? At what sampling rate?
Yes StarLab can log beam position. The BeamTrack sensors are thermal sensors. The power measurements for all Ophir power sensors are logged at 15 times a second. When a BeamTrack sensor is connected to StarLab via a Juno, the position / size measurements are also logged 15 times a second. When a BeamTrack sensor is connected to StarLab via a Vega/ Nova II, the position / size measurements are logged once a second. This is because in the Vega / Nova II we sample these parameters slower.
CloseAre BeamTrack sensors backwards compatible with the Nova-II, Vega and Juno devices?
The hardware of all of these devices supports the BeamTrack sensors however, the firmware may need to be upgraded. Click here for a free download of the latest firmware from our web site
CloseFor what type of laser spots can we measure position and size with BeamTrack sensors?
What meters support the BeamTrack (PPS) sensors?
Do I need to recalibrate my instrument? How often must it be recalibrated?
When using a BeamTrack sensor, is the response time for Position and Size measurements the same as it is for Power measurements?
The specified response time is only for the power and not for the size or position; response time is intentionally given in the Power section of the spec.
We haven't defined a position and size measurement response time because it depends on too many different parameters. For example:
- Small changes in size or position will respond quickly, large changes are much slower.
- Going from a large spot size to a smaller one is faster than going the other way.
- Position and size can change at the same time.
- If the power also changes it is even more complicated.
So the response time for size and position cannot be meaningfully specified by a single number. Having said all that, however:
In general, unlike the power reading which is accelerated by the predictive “speedup” function, the size and position measurements can't use the speedup so they are a bit slower.
The rise time for Position and Size is typically 5x – 10x the specified power response time.
Fall times for a decrease in power density (i.e. increase in size relative to power, as above) can be longer.
BeamTrack with StarLab
Support for BeamTrack sensors with Vega, Nova II, Juno, EA-1, StarLite, and StarBright in StarLab application is now available.
For all other meters and interfaces the BeamTrack sensor behaves like a standard thermopile sensor, and therefore it is not necessary to upgrade the embedded software of the sensor.
Download Steps
In order to upgrade the embedded software in the BeamTrack sensor with the StarLab application:- Attach BeamTrack sensor to a Juno (version 1.23 or higher), a Vega / Nova-II (version 2.28 or higher), a StarLite (version 1.22 or higher), or StarBright (version 1.30 or higher).
To download the latest version of Juno, Vega, Nova-II, StarLite or StarBright firmware press here - Connect the meter to the PC and run StarLab (with version 3.20 or higher).
To download the latest StarLab version press here - Enter the diagnostic screen and select to upgrade sensor firmware (version 1.05 or higher).

Note: BeamTrack sensors can't be upgraded via EA-1 interface.
- Attach BeamTrack sensor to a Juno (version 1.23 or higher), a Vega / Nova-II (version 2.28 or higher), a StarLite (version 1.22 or higher), or StarBright (version 1.30 or higher).

In this short “Basics” video we review in general how one goes about measuring laser beam power, so that you’ll have a clear basic understanding of what the different sensor types are, and when you would use which type.

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.
Ophir new 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.
