BeamPro Low-profile Beam Profiler

Our slim-line offers high performance in a small housing

The slim-line beam profiler series from Femto Easy can be used wherever space is limited. The BeamPro software STAR uses standard communication protocols and is therefore easily integrable in any environment. Several BeamPro can be controlled from a remote screen through the network.

190 – 1100 nm & 375 – 1100 nm


Space-saving slim-lines: Low-profile & micro-low profile


Exclusive with Femto Easy


Low-profile beam profiler

Up to 10 Mpixel in a small footprint is available with the low-profile series.

Micro-low profile beam profiler

Even tinier with up to 8 Mpixel is offered by our micro-low-profile series.

High performance in smallest space

1 The minimum beam diameters are specified for a precision of measurement better than 1%. Smaller beam diameter can be measured but the error will progressively increase.

2 Depending on the type of calculation, frame rate may vary.

3 Due to rolling shutter, the actual minimum exposure time to properly capture the whole beam will be limited by the laser beam size (in case of single-shot measurement) or by the laser repetition rate. For single-shot measurement : the larger the beam, the longer the required minimum exposure time. Otherwise, the slower the repetition rate, the longer the required minimum exposure time.

Optional Features

Windowless: Removal of the BeamPro sensor window to avoid potential interferences

UV extension: Increases the BeamPro wavelength range to the UV region, down to 190 nm

Additional ND filters:  The default BeamPro configuration includes one ND4 filter. Additional filter with different specifications can be ordered

Custom version on request: BeamPro is based on different types of cameras (resolution, pixel size, sensor material) and can be customized on request

High dynamic range: Software mode to increase the dynamic range of the BeamPro signal acquisition from 12 to 16 bits. Not compatible with pure single-shot measurements as 2 images are necessary to build one beam profile image

Vacuum compatible versions up to 10-8 mbar: Possibility to place the BeamPro and perform measurements directly inside a UHV vacuum chamber (not available for all models, please contact us for details)

Trigger: Synchronization of the BeamPro detection to an external signal for accurate laser single pulse measurement
