DF 040 HQ

Coherent Rofin‘s fibre-coupled multi-kilowatt diode laser is now available in a new HQ version (High Beam Quality). With an output power of 4 kW and a 600 µm fiber, the DF 040 HQ perfectly complements the DF Series as a cost-efficient tool for keyhole welding in addition to brazing and surface treatment that require higher beam quality. For multi-stage operation two switchable fiber outputs are optionally available. The modular design allows flexible power scaling, ensures high availability, and ease of maintenance. Further user-friendly features include industry standard control interfaces are offered for integration into production systems and a remote access for diagnostics.
