BeamPro Compact Beam Profiler

Beam Profiler with C-mount lens connection

Femto Easy BeamPro beam profiler provide ISO-compliant analysis and statistics on the spatial intensity distribution of laser beams. 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. They are suitable for wavelengths from 190 to 1100 nm and beams as large as 12 mm. High resolution models with pixel sizes as small as 1.85 μm for focused beam measurements are available.

375 – 1100 nm & 190 – 1100 nm

High Resolution up to 20 Mpx

Small pixel size down to 1.85 µm

C-mount and SM1 (adapter included)

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 ND filter (ND4). 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) can be customized on request

High Dynamic Range: Software mode to increase the dynamic of the BeamPro signal acquisition from 12 to 16 bits. Not compatible with pure single-shot measurement 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
