MKS Announces Ophir® Focal Spot Analyzer for Monitoring Material Processing Laser Performance
Andover, MA – January 22, 2018 – MKS Instruments, Inc. (NASDAQ: MKSI), a global provider of technologies that enable advanced processes and improve productivity, has announced the Ophir® Focal Spot Analyzer, a laser beam monitoring system that measures the focus spot and power of high power lasers in real time. The Focal Spot Analyzer measures focal spot size down to 37μm and laser power from <1 to 400 watts for wavelengths from 266 – 1100nm. Designed for laser applications with shorter working distances, the system monitors power density distribution of the focal spot and shifts in the focal plane location, and provides a well understood location of the laser caustic. It is so accurate that the distance to the camera array is NIST traceable. This is critical for applications that require a focused spot of light with a welldefined, narrow, and reproducible bandwidth and intensity profile, including medical device manufacturing and microwelding.
