How to clean the laser protection optical lens for laser engraving machine?
Optical Spherical Lens Supplier shares that although the laser tube and lens of the laser engraving machine are consumable, we always hope to replace less, so as to extend the service life of the laser tube and reduce the cost.
In the laser engraving machine lens replacement process, lens placement, detection, installation and other processes, should pay attention to the lens from damage and pollution. After a new lens is installed, it needs to be cleaned regularly. The process is fairly straightforward. If done correctly, it will be extended effectively
Lens life, and reduce the cost. On the contrary, it will reduce the service life.
It is inevitable that the optical elements in the laser tube will come into contact with the suspended objects when the laser engraving machine is working. When the laser cuts, welding and heat treatment materials, the working surface will release a lot of gas and spatter, which will cause damage to the lens.
When the contaminant falls on the surface of the lens, it absorbs energy from the laser beam, causing the thermal lensing effect. If the lens has not formed thermal stress, the operator can remove it and clean it. Of course, something should be done to avoid damaging the lenses and further contamination.
General rules of operation:
During the installation and cleaning of the lens, any sticky material, even nail prints or oil droplets, will increase the absorption rate of the lens and reduce its service life. Therefore, the following precautions must be taken:
1. Do not use bare finger lens installation, should wear gloves or rubber gloves.
2. Do not use sharp instruments to avoid lens surface scratches.
3. Do not touch the film when taking the lens, but hold the edge of the lens.
4. The lens should be tested and cleaned in a dry and neat place, with several layers of cleaning paper towels or paper swabs, and several sheets of lens cleaning tissue paper.
5. Users should avoid talking above the lenses and keep food, drink and other potential pollutants away from the working environment.
