Technology Summary

Laser Beam Profiler

The Laser Beam Profiler is a high precision CCD camera based measurement tool for measuring lasers in the VIS and NIR wavelength range. It offers high camera pixel counts of 1600 x 1200 with small pixel dimension of 4.4 Ám x 4.4 Ám or 2752 x 2192 pixels with pixel dimension of 4.54 Ám x 4.54 Ám, and fast USB 3.0 interface. It can operate with USB 3.0 ready PC for fast laser beam measurement. It has high dynamic range with software auto shutter control to minimize laser saturation to the camera. Our powerful software of version 5.1 can perform over 50 laser beam measurement functions including peak and centroid identification, zooming measurement and display, Gaussian fitting, beam width measurement, 3D display, beam comparison, and other additional functions like interference fringe spacing and beam alignment. The Laser beam profiler makes quick laser beam quality assessment.

The Laser beam profiler can identify spatial characteristics (including beam width, divergence, and direction) of a laser beam and help system designer to plan and predict the utility of the laser beam. The Laser beam profiler is important for laser manufacturers for quality control.

Medical and industrial laser applications such as laser printing, welding, cutting, and fiber optics beam coupling all require using the Laser beam profiler for quality control and system design. Using the Laser beam profiler can help improve the laser coupling efficiency, power management, laser beam/tissue interaction, and laser cutting quality.
