Femto Easy, ultrafast instrumentation

BeamPro beam profiler

Beam Profilers are devices that allow the whole optical intensity profile measurement of a laser beam. They retrieve not only the beam diameter and position, but also the full shape of the beam.

We provide two types of BeamPro beam profilers :

  • BeamPro with large sensors, to measure collimated beams.
  • BeamPro with small pixels, to measure focused beams.

The Femto Easy BeamPro takes advantage of our user-friendly software, and provides thorough analysis and statistics of your laser beam. The BeamPro software uses standard communication protocols. It is therefore easily integrable in most complex environments. Several BeamPro can be controlled from a remote screen through network. They are suitable for wavelength from 190 to 1100 nm and sensor size is up to 25 mm. There are also high resolution models with pixels as small as 1.85 μm for focused beam measurements.

Features

  • Compact design
  • Marker indicating chip location
  • Two wavelength ranges available
  • Neutral Density filters available
  • C-mount
  • Windowless option available
  • Custom versions available on request
  • User-friendly and powerful software (STAR : Software Technology for Acquisition and Retrieval)

Options

Option Description
Additional ND filters The default BeamPro configuration includes one ND filter. Additional ones with different specifications can be ordered
Custom version on request BeamPro based on different type of camera (resolution, pixel size, sensor material) can be developed 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
Trigger Synchronization of the BeamPro detection to an external signal for accurate laser single pulse measurement
UV extension Increases the BeamPro wavelength range to the UV region, down to 190 nm
Windowless Removal of the BeamPro sensor window to avoid potential interferences

Software

Like every Femto Easy product, the BeamPro comes with a powerfull and very user friendly software, especially designed for touch screens, in order to give you the best user experience.
