Due to the working environment, the optical lens of the fiber laser marking machine may be contaminated. Therefore, after a period of use, if not maintained in time, dust will corrode the lens coating.
The lens with damaged coating cannot reflect light and cannot pass through the laser. On the contrary, it will absorb the heat of laser, affect the marking effect, and easily crack the lens.
So how to maintain the lens of fiber laser marking machine?
Maintenance tips for optical lenses
1. The lens should be wiped gently without damaging the surface coating.
2. During the wiping process, it should be handled with care to prevent slipping.
3. Do not wipe the lens back and forth, and do not scrub with rough materials.
4. Wipe with absorbent cotton can only be used once. Check that no cotton threads or other residues are left behind. Before starting the machine, the alcohol should be completely evaporated.
