Laser Cleaning
How Does Laser Cleaning Work?
Laser cleaning uses a focussed laser beam that causes surface contaminants like rust, paint or residue to absorb the energy, evaporate or break apart and lift off while the base material remains unaffected. The method is highly precise and localized, perfectly suited for delicate components and intricate surfaces. To ensure thorough and even cleaning the laser beam is moved across the surface using a scanning system typically with galvanometer scanners. These fast moving mirrors direct the beam in controlled patterns, such as lines; covering the targeted area efficiently. The scan speed, beam, intensity, and pattern are all adjustable and enabling optimized cleaning for different materials and contamination levels.
Laser beam hits the surface
Our lasers emit light in short pulses in the nanosecond range. The process is gentle on the material, as the heat input to the workpiece is reduced to a minimum.
The radiation heats up the oxide layer
Our lasers work with a wavelength of approximately 1064 nm. This light is well absorbed by layers of dirt or paint, but not by the workpiece.
The surface is cleaned by blasting off the contamination
Accessories such as our extraction system remove particles directly from the workpiece and from the air, making the laser process very clean.
