The focusing lens of the laser cutting machine is a relatively precise optical component, and its cleanliness directly affects the processing performance and quality of the laser cutting machine. If the lens is not properly selected, it will cause large laser loss, frequent damage to the protective lens, and unstable product quality, causing serious losses to the enterprise. Although the protective lens of the laser cutting machine is a wearing part, in order to improve its utilization rate and reduce the production cost, the lens can be cleaned by regular cleaning to achieve the purpose of recycling. The following laser lens maintenance skills are share by Dingxin Sheng Technology:

In general, the laser cutting machine focusing lens needs to be checked before usage, also before and after cleaning. Because most contaminants and surface defects are relatively small in size, we always need to use amplification equipment when inspecting lenses. In addition to amplifying equipment, sometimes we need to use a relatively bright light to illuminate the optical surface, enhancing the specular reflection intensity of surface contaminants and defects, which makes it easier to spot contaminants and defects.

When cleaning laser cutter focusing mirror, clean wipes and optical grade solvents are often used to prevent damage from other contaminants. Wipe paper must be wetted with suitable solvent and must not be used if dry. In consideration of softness, the available wiping paper is cotton Webril wiping paper or an applicator such as cotton ball, lens paper, and cotton swab.
