To maintain the focus lens of laser cutting machine, the following three points should be paid attention to:
1. The focus lens material is ZnSe (arsenic zinc oxide), which is brittle and afraid of falling. During disassembly and assembly, attention shall be paid to: do not use too much force to collide with hard objects. There is antireflection film on the surface, so it is required to provide dry and degreased air in the work. Do not directly handle the lens of the laser cutting machine focus lens by hand, because the skin grease will cause permanent damage to the lens surface. It can be operated with gloves and special sets. For smaller lenses, it is more convenient to use optical tweezers or vacuum tweezers. No matter what method is used to clamp the focus lens of laser cutting machine, it can only be clamped along the non-optical surface, such as the frosted edge of the lens edge.
2. When cleaning the focus lens of a laser cutting machine use clean wiping paper and optical grade solvent to prevent damage by other pollutants. Wipe paper must be moistened with a suitable solvent and must not be used dry. For the consideration of softness, the available wiping paper is pure cotton wiping paper or cotton ball, lens paper, cotton swab and other applicators.
3. In general, before and after use and cleaning, it is necessary to check the focusing lens of laser cutting machine. Because the size of most pollutants and surface defects is relatively small, we often need to use amplification equipment when checking the lens. In addition to amplification equipment, sometimes we need to use a relatively bright beam of light to irradiate the optical surface to enhance the specular reflection intensity of surface pollutants and defects, so that pollutants and defects can be more easily found.leapion
