Laser cleaning uses the high energy and narrow pulse width of the laser to instantly vaporize the adhered material or rust on the surface of the cleaned workpiece without damaging the workpiece itself. Commonly used optical solutions: the laser beam scans the working surface through the galvanometer system and the field lens to clean the entire working surface. It is widely used in metal surface cleaning, and laser light sources with special energy can also be used in non-metal surface cleaning.
Carmanhaas offer professional laser cleaning system. The optical components mainly include QBH collimating module, galvanometer system and F-Theta lens.
The QBH collimation module realizes the conversion of divergent laser beams into parallel beams (to reduce the divergence angle), the galvanometer system realizes beam deflection and scanning, and the F-Theta field lens realizes uniform scanning and focusing of the beam.
1. The film damage threshold is 40J/cm2, which can withstand 2000W pulses;
2. Optimized optical design guarantees long focal depth, which is about 50% longer than conventional systems with the same specifications;
3. It can realize the homogenization of the laser energy distribution to ensure the cleaning efficiency while avoiding the damage of the material substrate and the edge thermal influence;
4. The lens can achieve a uniformity of more than 90% in the full field of view.
