BeamOn WSR-Laser Beam Analysis

BeamOn WSR-Laser Beam Analysis

Wide Spectral range 190nm to 1600nm CCD Beam Profiler

Complete system for Laser Beam Analysis, composed of a CCD camera head, a set of 4xND filters (ND8, ND64, ND200, and ND1000) in housing, a USB 2.0 interface, software on CD disk, carrying case, user manual on CD.

The BeamOn WSR system is a beam diagnostics measurement system for real-time measurement of continuous or pulsed laser beams. It measures laser beam parameters, such as: intensity profiles, beam width, shape, position and power. Software also provides report function for beam analysis settings and results.


The system is based on a USB interface, software driven device, which can be connected to a Notebook (or Desktop) computer via the High Speed USB 2.0 port and run on Windows 7 / 8 / 10 OS (32 & 64 bit).


The CCD profiler over comes the limited dynamic range of camera type Beam profilers .Each measurement is performed at a different attenuation or electronic shutter speed. Duma patented technology enables the users to view features that are smaller than 1% of the laser beam’s maximum power density.
