Laser lens is divided into focusing lens, protection lens and other types of lenses, in its working process to avoid some pollution, such as water pollution and dust pollution, then the daily maintenance process needs to be cleaned laser lens to ensure the stability of the laser cutting machine.

The principle of carbon dioxide laser cutting machine is to use the vibration of carbon dioxide molecules and the transition between rotating energy levels to produce laser.The discharge tube of carbon oxide laser is filled with mixed gases such as carbon oxide, whose ratio and total pressure can va
