Request InfoMKS Instruments Inc.The Ophir® WB-I SWIR Wide Beam Imager from MKS Instruments Inc. is a compact, calibrated optical system for measuring the size and power distribution of large and divergent beams of VCSELs and LEDs in the SWIR range. The profiler, when combined with Ophir BeamGage software and an InGaAs camera, is capable of imaging any beam shape that is too large for a camera sensor. It features a 45-mm diameter aperture and can accurately measure beams with an angle of incidence up to 70°. Beams are captured on a translucent diffusive screen and then re-imaged to produce a complete and...See full productRelated content from Photonics MediaPRODUCTSPhotonics.com 11/2/2021Laser Propagation SystemThe latest Ophir® M2 BeamSquared® laser propagation system from MKS Instruments Inc. automatically and accurately measures the propagation characteristics of continuous wave and pulsed lasers...BioPhotonics Nov/Dec 2022 IssueBeam Profiling CameraThe Ophir SP504S Beam Profiling Camera from MKS Instruments Inc. measures large and divergent beams by accurately capturing and analyzing wavelengths from 340 to 1100 nm for beam sizes from 45...Photonics Spectra April 2022 IssueBeam ProfilerThe Ophir® SP932U USB 3.0 High-Resolution Beam Profiler from MKS Instruments Inc. is a compact, CMOS camera-based beam profiler for UV, VIS, NIR, and Nd:YAG wavelengths that deliver accurate...Photonics.com 4/26/2022Laser Power SensorThe Ophir® IPM-10KW laser power sensor from MKS Instruments Inc. delivers high accuracy and repeatable measurements in rough production environments.
