How does the laser cutting machine clean the protective lens regularly？
Laser cutting machine cleaning protection lens, how to better clean, as a fiber laser cutting machine manufacturer, let us jointly understand how the laser cutting machine is regularly clean protection lens!
1. The protection lens material is ZnSe (zinc arsenic), which is brittle and afraid of falling; In the disassembly should pay attention to: can not be too hard, can not collide with hard objects. Surface anti-reflection film, afraid of pollution, afraid of wet, afraid of oil, afraid of scraping; Therefore, it is required to provide dry, oiling air at work. Do not directly handle the lens of the laser cutting machine by hand to protect the lens, because the skin oil will cause damage to the lens surface.
Instead, you can wear gloves and their special cover to operate, and for smaller lenses, optical tweezers or vacuum tweezers are more convenient. No matter what method is used to clamp the laser cutting machine to protect the lens, it should only be clamped along a non-optical surface, such as the frosted edge of the plaque.
2. Generally, it is necessary to check the protection lens of the laser cutting machine before use and before and after cleaning. Because the size of most contaminants and surface defects is relatively small, we often need to use magnification equipment when inspecting lens.
In addition to the amplification equipment, sometimes we need to illuminate the optical surface with a brighter beam of light to enhance the specular reflection intensity of contaminants and defects on the surface, so that pollutants and defects can be found more easily.
3. When cleaning a laser cutting machine protection lens, always use clean wipe paper and optical grade solvent to prevent damage by other contaminants. Wipe paper must be wet with a suitable solvent, must not be used dry. For the consideration of softness, the available wipe paper is pure cotton wipe paper or cotton ball, lens paper, and cotton swab and other applicators.
