BeamPro One-Inch Beam Profiler

Beam profiling for large beams up to 25 mm in diameter

Femto Easy BeamPro Once-inch provides ISO-compliant analysis and statistics on the spatial intensity distribution of large area 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 375 to 1100 nm and beams as large as 25 mm in diameter.

375 – 1100 nm

Large beam aperture of 25 mm

Perfectly suited for highly divergent beams, VCSEL or laser diodes


One-Inch Beam Profiler

Equipped with a one-inch sensor, this beam profiler is the right partner for large beam diameters.


User-friendly software & electronics design

BeamPro can be controlled from a remote screen through network connection.

High performance One-inch format

Optional Features

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

High dynamic range (16 dB): 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

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