November 11, 2026 – Andover, MA – MKS Inc. (NASDAQ: MKSI), a global provider of enabling technologies that transform our world, has announced the Ophir® BeamPeek^® 2 high power beam analysis and power measurement system. Designed for fast, accurate real-time analysis of lasers in additive manufacturing and laser welding, Ophir BeamPeek 2 simultaneously measures beam profile, focal spot, beam caustic / M², and power in under three (3) seconds. It tracks these parameters over time to support consistent part quality. Unlike large, complex industrial units that require water cooling, Ophir BeamPeek 2 is a compact, rugged system that can be easily incorporated into a production line without interrupting the production process. It features passive cooling, a built-in beam dump cartridge, and expanded durability for longer operating times and higher power levels – up to 2 kW for 1 minute or 1 kW for 2 minutes for 1030–1080 nm NIR lasers.

The patented Ophir BeamPeek 2 laser analysis and power measurement system is an easy-to-use, integrated system. It combines a beam profiler camera, power meter, beam dump, beam splitters, and optics in one industrial system. Ideal for field service testing of additive manufacturing and welding chambers, there is no need for water or fan cooling as the system includes a replaceable passive cooling beam dump tray that eliminates downtime between measurement sessions. A dustproof, replaceable window allows operation in the presence of metal powder residuals.

For AM system manufacturers and their field service teams, the Ophir BeamPeek 2 system brings focal spot, beam caustic and power measurements together in one unit. Build-plane-referenced focal spot measurements and tracking of spot size and power over time provide a common view of laser performance for engineering analysis and field service testing.

The Ophir BeamPeek 2 system is supported by an array of software options:

(a) Ophir BeamPeek software for M² (caustic diagnostics), focal spot size and position calibrated to build plane, changes in spot size & power over time, Rayleigh length, divergence, waist width, location, and ellipticity.

(b) Ophir Ring-Core BeamGage® software for ring-core laser beams.

(c) Ophir BeamGage Professional software, the industry’s most advanced beam analysis system, which provides deeper beam-parameter and statistical analyses.

Availability
The Ophir BeamPeek 2 high power laser analysis and power measurement system for additive manufacturing is available now.
