How to Choose Fiber Laser Protective Window?

Ⅰ. Introduction of the fiber laser protective window

As the name suggests, the fiber laser protective window is used to prevent dust and slag splash from damaging the focusing lens. In addition to the application of the fiber laser protective window in the laser cutting machine, it is also necessary in other laser equipment including laser marking and laser welding as well as laser engraving and so on. It can be seen that the application market for fiber laser protective windows is very large.

When cleaning the fiber laser protective window, clean wiping paper and optical-grade solvent are often used to prevent damage by other contaminants. The wipe paper must be moistened with a suitable solvent, and it must not be used dry. For the consideration of softness, the usable wipes are pure cotton wipes or cotton balls, lens tissues and cotton swabs.

The price and quality of fiber laser protective windows on the market are not the same. Of course, it is not uncommon to see shoddy windows. If the fiber laser protection window is not properly selected, it will cause large laser loss, frequent damage to the fiber laser protection window, unstable product quality, and cause serious losses to the enterprise. Therefore, choosing the right fiber laser protective window is a matter of great importance.

Ⅱ. How to choose fiber laser protective window

1. The shape and size of the optical fiber laser protective window should be matched.

2. When choosing the materials of the optical fiber laser protective window, customers can buy K9 and quartz according to different laser power and cost. In the actual application process, professional manufacturers divide the two types of materials into multiple grades. Customers can choose corresponding specifications according to actual needs. 

3. The coating of fiber laser protective window and laser antireflection coating adopt different coating technical parameters according to the use environment.
