Variable Spot Laser Hardening Head
The VarioSpot™ Variable Beam Laser Hardening Head is engineered for precision laser surface hardening applications requiring adjustable beam size and flexible heat treatment control. Designed with a rectangular, variable spot profile, this laser hardening head enables precise energy distribution for optimized quenching depth and uniform surface treatment.
Its long focal length configuration supports large working distances and internal diameter processing, making it ideal for shafts, molds, heavy-duty components, and large structural parts. The fully water-cooled body and nozzle structure ensure reliable thermal management under high-power laser operation.
Fully water-cooled body and powder nozzle design for superior thermal stability during high-power laser hardening
