Ophir Optics, IR OpticsThe FGC100 NIST-traceable LED calibration standard from Ophir Optics LLC has been announced by MKS Instruments Inc. It is designed to calibrate the Ophir FluxGage system. FluxGage is a compact, all-in-one LED luminaire measurement system that measures flux, color and flicker, important quantities for evaluating the performance of LED-based products. FluxGage is used instead of large, cumbersome integrating spheres during development and production, as well as for incoming inspection and quality control of new and replacement parts, allowing LED luminaires and modules to be sorted for...See full productRelated content from Photonics MediaPRODUCTSPhotonics Spectra September 2022 IssueMWIR Continuous Zoom LensThe Ophir® LightIR 18- to 225-mm MWIR f/4 continuous zoom lens from MKS Instruments Inc. is a compact thermal imaging lens optimized for 10-µm SXGA/HD and 15-µm VGA focal plane array...Photonics Spectra May 2024 IssueReplicated Freeform MirrorsThe Newport™ Replicated Freefrom Mirrors from MKS Instruments are nonrotationally symmetric reflective mirrors for use in analytical instruments, imaging systems, laser tracking, and...Vision Spectra Winter 2023 IssueCompact IR Zoom LensThe Ophir® FoldIR 30 - 450 mm f/3.4 continuous zoom lens from MKS Instruments Inc. is a long-range, compact folded optics IR zoom lens for gimbal systems and payloads in air-land-sea...Vision Spectra Summer 2023 IssueSwir LensThe Ophir LightIR 10-135 mm and 18-225 mm MWIR f/3.6 continuous zoom lenses from MKS Instruments Inc. are compact, high-performance, motorized continuous zoom lenses.
