Positioning module

Product overview
Coupling lenses precisely align the CCD optical path and the laser optical path. Galvo scanning is digitally mapped to the CCD position matrix, and coordinate-mapping algorithms correct drift and distortion introduced by the F-theta lens. This enables accurate CCD positioning across the entire galvo scanning field without external X and Y axis movement.

Product advantages

• Axis-free precision: Eliminates motion-induced positioning errors and enables precise alignment for laser welding without relying on external X/Y stages.
• Static full-field operation: Wide-field galvo scanning at high speed while the workpiece remains stationary; recognition and welding can be synchronized to improve throughput.
• Long-term stability: One-time calibration with proprietary digital-calibration algorithms compensates for lens drift and F-theta distortion, reducing the need for repetitive recalibrations.
