How to choose the focus lens of laser cutting machine?

When we use fiber laser cutting machine to cut metal plates of different thickness, we should not only select the appropriate power equipment, but also pay attention to the selection of focusing lens. Maybe some people are a little strange, isn't the fiber laser cutting machine adjusted to be able to be directly used for processing? Next, I'll explain it to you!

There are many kinds of vulnerable parts in laser cutting machine. Today, I mainly introduce the protective lenses in laser cutting machine.

As the name implies, protective lens is used to prevent the focus lens from being damaged by dust and slag splashing. In addition to its application in laser cutting machine, it is also necessary in other laser equipment, including laser marking, laser welding and laser carving. It can be seen that the application market of protective lenses is very large.

The price of protective lenses on the market varies from tens of yuan to hundreds of yuan, and the quality is also different. Of course, it is not uncommon to see inferior lenses. If the lens is not selected properly, it will cause large laser loss, frequent damage to the protective lens, unstable product quality, and serious losses to the enterprise. Therefore, choosing the right protective lens is a very important thing.
