Andover, MA – July 22, 2019 – MKS Instruments, Inc. (NASDAQ: MKSI), a global provider of technologies that enable advanced processes and improve productivity, has announced the Ophir® 16K-W High Power Laser Sensor, a compact sensor for measuring very high power lasers. The water-cooled thermal sensor measures powers from 100W to 16kW over the spectral range of 0.8µm to 2µm and 10.6µm. A relatively large, 55mm aperture is insensitive to beam size or angle of divergence. The sensor delivers a fast, 3.5 sec response time. A deflecting cone and annular absorber can withstand high power densities to 10kW/cm2.
