PSC Metis H3 Series

Ultra-High-Speed Pyrometer for Laser Process Control

The Metis H3 Series is an ultra-high-speed pyrometer series, available in 1- and 2-colour wavelength versions, covering temperature ranges from 120°C to 3300°C. High-speed pyrometers of the Metis H3 series measure temperatures many times faster than traditional IR temperature sensors, delivering all the advantages of digital data processing while maintaining high accuracy with high-speed outputs via analogue and digital circuitry.

The H3 series measures temperature directly at the laser welding spot, with the analogue or digital output used to control laser power and maintain the required temperature level — a unique, stand-alone concept in a compact design for combined temperature measurement and laser control.

Key Features

• H316, H318, H309 (1-colour): Exposure time <20µs, more than 50,000 measurements per second.
• 2-colour models: Exposure time <40µs, more than 25,000 measurements per second — response times of 40 and 80 microseconds respectively, fast enough for near real-time laser heating, annealing and cladding control.
• Sighting/aiming methods: through-lens, colour video, or laser aiming.
• Optics can be coupled into the beam path of the laser machine’s optics, or externally mounted with its own focusable lens.
• Operates and communicates autonomously via digital inputs to feed information to the control loop for adjusting laser power.

Software

SensorTools software is used for measurement and recording for evaluation purposes, supporting both fully autonomous operation and remote-control commands via existing systems.

Applications

Purpose-built for laser welding, laser heating, annealing, cladding and other applications requiring near real-time temperature feedback to control process equipment.
