MKS Instruments, Inc., has announced the a compact calibrated optical system for measuring the size and power distribution of large and divergent beams of VCSELs, LEDs, edge emitting lasers, and fiber lasers. The Wide Beam Imager device is capable of imaging any beam shape (round, line, or square) that is too large for a camera sensor. It features a 48mm diameter aperture and an angle of incidence of 70 degrees. Beams are captured on a translucent diffusive screen and then re-imaged to produce a complete and accurate mapping of the light's intensity distribution. The WB-I is designed for use with camera-based beam profiling systems in development and testing of applications such as VCSEL-based LiDAR, high speed data communication solutions, 3D sensing, autofocus systems, and machine vision,
The Wide Beam Imager is a compact device that is quick to install, easy-to-use, and dust-proof. Unlike low accuracy, do-it-yourself devices or slow and expensive goniometers, the Wide Beam Imager produces images with reduced speckle and high accuracy measurements of power distribution.
The Wide Beam Imager device is supported by Ophir BeamGage Professional software, the industry's most advanced beam analysis system. BeamGage is based on Ultracal, Ophir's patented, baseline correction algorithm that helped establish the ISO 11146-3 standard for beam measurement accuracy. BeamGage software includes all the calculations needed to make accurate, ISO approved laser beam measurements, including total power, peak fluence, ellipticity, goodness of fit, and more. The software provides advanced image processing features, NIST-traceable power measurements, trend charting, data logging, pass/fail production testing, and multilingual support for English, Japanese, and Chinese. Advanced features include partitioning of the camera output for separate analysis of multiple laser beams from sources such as fiber, a .NET interface for full remote control when integrating beam analysis into an automated application, and camera sharing.
