The protective lens in the fiber laser cutting machine is mainly used to prevent dust and slag splashing from damaging the focusing lens. In addition to the application on fiber laser cutting machines, it is also required in laser equipment such as laser marking machines, laser welding machines, and laser cleaning machines.

 

Although the protective lens of the fiber laser cutting machine is a consumable item, cleaning the protective lens regularly can achieve the purpose of repeated use, thereby prolonging the service life of the lens and improving its utilization rate. Here are the steps to clean the protective lenses:

 

The protective lens material is ZnSe (arsenic zinc), which is brittle and afraid of falling. Therefore, be careful not to use excessive force during disassembly and assembly, and do not collide with hard objects. There is an anti-reflection coating on the surface of the protective lens, so it is afraid of pollution, so pay attention to moisture-proof, oil-proof and scratch-proof. Never touch the protective lens of the laser cutter directly with your hands, as skin oils can permanently damage the lens surface. Instead, you can do it with a hand suit on. For smaller lenses, it is more convenient to use optical tweezers or vacuum tweezers.

In general, lens conditions need to be checked before use and cleaning of protective lenses. Because most contaminants are relatively small, we often need to use magnifying equipment when examining protective lenses. In addition to magnifying the device, we sometimes need to illuminate the optical surface with relatively bright light to enhance the specular intensity of surface contamination and defects, making them easier to spot.

When cleaning the protective lenses of your laser cutter, always use a clean rag and optical grade solvent to prevent damage from other chemicals. Wipes must be moistened with a suitable solvent and must not be used in a dry environment.

 

Good maintenance of every part in the fiber laser cutting machine can ensure the high precision cutting and longer service life of the machine. For more laser machine information, you can communicate online.
