Andover, MA – September 23, 2020 – MKS Instruments, Inc. (NASDAQ: MKSI) has announced the Ophir® Wide Beam Imager (WB-I), 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.
