How to choose laser protective lenses

When a laser cutting machine cuts metal materials, a large amount of gas, slag, and splashes are released from the working surface. Maintaining the lens is used to prevent damage to the aggregated lens during the cutting process. Of course, it is not only used for laser cutting machines, but also for laser welding, marking, engraving and other laser equipment, so the market for maintaining lenses is very strong.

On the back of strong market demand, there are generally uneven product prices and quality. The maintenance lenses on the market range from tens to hundreds, and the price difference is naturally due to the significant difference in quality. Therefore, choosing lenses with good quality and low laser loss is very important for enterprises in the metal processing industry.

In addition to matching the external dimensions, it is also necessary to choose the appropriate raw materials for maintaining the lenses and the technical parameters of the laser anti reflective film based on the actual cutting environment and laser cutting power.

If choosing and maintaining lenses is a mental task, then using and maintaining lenses is a technical task.

During the installation and cleaning process of maintenance lenses, any sticky material, even nail polish droplets, will increase the absorption rate of the lenses and reduce their service life. So the cleaning work of lenses cannot be ignored:

1. Gloves must be worn during installation, and no fingerprints should be left behind;

2. Do not let anything scratch the surface of the lens;

3. When taking the lens, hold the edges of the lens with both hands and do not touch the film layer;

4. Clean the lenses with clean cotton paper, wiping strips, and optical grade solvents;

Maintaining lenses is just a small loss for laser cutting machines, but it cannot be ignored. The above precautions for selecting lenses and operating are provided for reference by users of laser cutting machines!
