MKS launches Ophir BeamPeek 2 for laser beam analysis

MKS Inc. has introduced the Ophir® BeamPeek® 2, an integrated laser beam analysis and power measurement system designed to support process monitoring and quality control in additive manufacturing (AM) and laser welding applications.

Announced on November 9, 2026, the system enables manufacturers and service engineers to measure key laser parameters, including beam profile, focal spot size, beam caustic (M²), and laser power, in less than three seconds. By tracking these measurements over time, the technology helps users assess laser performance, identify potential variations, and maintain consistent processing conditions.

The Ophir BeamPeek 2 is designed for use in additive manufacturing chambers and industrial laser welding environments, where accurate beam characterization is essential for process stability and component quality. The system supports near-infrared (NIR) lasers operating at wavelengths of 1030–1080 nm, with power-handling capabilities of up to 2 kW for one minute or 1 kW for two minutes.

Unlike conventional industrial beam measurement systems that require external cooling arrangements, BeamPeek 2 features a compact design with passive cooling. Its integrated beam dump cartridge eliminates the need for water or fan cooling, simplifying installation and maintenance in production environments.

Integrated Measurement for Industrial Applications

The system combines a beam profiler camera, power meter, beam dump, beam splitters, and optical components within a single industrial unit. This integrated configuration enables laser performance measurements without the need for multiple standalone instruments.

For additive manufacturing equipment manufacturers and field service teams, BeamPeek 2 provides focal spot, beam caustic, and power measurements referenced to the build plane. These capabilities allow engineers to evaluate laser alignment, monitor changes in beam characteristics, and assess performance during equipment servicing and process verification.

The system also incorporates a dustproof, replaceable protective window, allowing measurements in environments where residual metal powder may be present. A replaceable passive-cooling beam dump tray supports repeated measurement sessions while reducing maintenance requirements.

Software Support for Beam Characterization

MKS offers several software options to support different levels of laser beam analysis.

The Ophir BeamPeek software provides measurements of M², focal spot size and position relative to the build plane, Rayleigh length, beam divergence, waist width, beam location, and ellipticity. It also enables users to track changes in spot size and laser power over time.

For applications involving ring-core laser beams, the system supports Ophir Ring-Core BeamGage® software, while Ophir BeamGage Professional provides additional beam parameter analysis and statistical evaluation capabilities.

These software tools enable manufacturers to examine laser beam characteristics in greater detail, supporting equipment diagnostics, process development, and quality assurance.

Supporting Laser Process Consistency

As additive manufacturing and laser welding applications continue to demand greater precision and repeatability, reliable laser beam measurement plays an important role in maintaining stable production conditions.

By combining multiple measurement functions in a compact, integrated platform, Ophir BeamPeek 2 provides manufacturers and service engineers with a practical solution for evaluating laser performance and identifying changes that could affect processing results.

The Ophir BeamPeek 2 high-power laser analysis and measurement system is now commercially available.
