Fiber laser cutting machine is very popular in industrial applications as an efficient metal cutting equipment. Among them, the protective lens also plays an important role as a consumable of the fiber laser cutting machine. In addition to the application of fiber laser cutting machines, protective lenses also play an important role in other laser equipment such as laser marking machine, laser welding machine, and laser cleaning machine.
Laser protection lenses on the market vary widely in price and quality. So how do you choose the right protective lens for your laser equipment?
1. The external dimensions are matched.
2. Lens material. Users should choose K9, quartz according to different laser power and considering the cost of use. In the actual application process, professional manufacturers divide these two types of materials into multiple grades, and customers can choose corresponding specifications according to actual needs.
3. Adopt different coating technical parameters according to the use environment.
4. Under normal circumstances, the thickness of the lens is low and the laser transmittance is high. But sometimes in order to prevent the lens from being damaged by the gas pressure ejected by the laser cutting machine, a thicker lens must be used.
