Note Please

The thickness of CO2 conventional lenses on the market are all 2mm, which is not a thin lens, please rest assured.

Please pay attention to the power of your machine, generally CVD lens can support 200W high power machine, China PVD lens can support 80W machine.

Generally, the burnout of the lens may be caused by the following reasons: your optical path is not correct, the air pump is not turned on when working, or the surface of the lens is polluted, there is condensation on the surface, and the material is defective, etc., which may cause the lens to be burned through.

Cautions:

1. Make sure the optical path is corrected (how to adjust the optical path pdf can be chat us)

2. Remember to turn on the air pump when working

3. Make sure the lens is clean and free from condensation

4. Material issues, etc.
