What is Laser Cleaning?

Laser cleaning is the process of removing materials from surfaces using a laser beam.

When the laser beam contacts a surface, light is absorbed by the surface. When the ablation threshold is hit, molecular bonds in the surface are broken and ejected from the substrate (“vaporized”).

Features of Laser Cleaning

1. Non-contact cleaning, little damage to the base substrate layer.

2. Precise cleaning: Able to clean specific areas using pre-defined beam parameters.

3. Selective cleaning: Able to remove different types of materials individually, based on the ablation threshold.

4. High cleaning efficiency.

5. Stable and compact design, with minimal maintenance efforts.

6. Easy to operate: Can be used by operator or integrated with a robotic arm for automated cleaning.

7. No need to use chemicals, waters or other cleaning mediums. No consumables, safe and environmentally-friendly.
