Galvo Scanner with Integrated Pyrometer Brings Benefits to Plastic Welding

The COMPACT Series is a range of air or water cooled, fibre coupled, high power diode laser systems with output power up to 500W. The galvo scanner is a fast 2 axis beam deflection unit, and when combined with the pyrometer, offers significant benefits in the field of quasi-simultaneous plastics welding. The on-axis single colour pyrometer allows the temperature of the welding zone to be optically measured during the scanning process, thus enabling closed-loop temperature control of the production process. The supporting software supplied with the unit captures process data for documentation and quality control purposes.

The galvo scanner is available with apertures of 20mm or 30mm diameter and can be used in combination with 200μm or 400μm fibres and F-Theta optics, keeping the beam spot focused. The beam diameter is 1.4mm or 2.8mm depending upon the fibre diameter used and the unit provides a working field of 140mm x 140mm.

This new DILAS galvo scanner with its integrated pyrometer is supplied as a package which includes - colour-corrected F-Thetha optics, pyrometer, fibre coupled collimating unit, a control unit and scanner plus pyrometer software.
This new product offering further compliments Rofin’s complete range of laser systems which include CO2, YAG, Vanadate and Fibre Lasers. Rofin also provides solutions for laser cutting, welding and marking applications.
