There are three steps to choose the
Protective Lens of
Laser cutting machine:
1) The shape and size match, which is easy to understand;
2) Material, according to different laser power, considering the cost of use, you can choose K9, quartz, in the actual application process, professional manufacturers will be divided into multiple grades of these two materials, customers can choose the corresponding specifications according to the actual needs.
3) coating, laser anti-reflective film, according to the use of different coating technical parameters.
Although the protective lens of
Laser Cutting Machine belongs to the wearing parts, but in order to improve its utilization rate and reduce the production cost, the protective lens can be cleaned regularly to achieve the purpose of reuse. The following are three cleaning steps summarized by high-energy laser:
1. Protective lens material is ZnSe (Arsenic zinc), which is brittle and afraid of falling; Attention should be paid to the disassembly: not too hard, not collision 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 in the work, do not directly
Handle the
laser cutting machine to protect the lens of the lens, because the skin grease will cause permanent damage to the lens surface. Instead, you can operate with gloves and a special
cover. For smaller lenses, optical tweezers or vacuum tweezers are more convenient. No matter what method you use to clip the laser cutter to protect the lens, only clamp it along a non-optical surface, such as the frosted edge of the lens plaque.
2. In general, before and after use and cleaning need to check the laser
cutting machine protection lens. Due to the small size of most contaminants and surface defects, we often need to use magnifying equipment when examining lenses. In addition to amplifying equipment, it is sometimes necessary to shine a relatively bright light on an optical surface to enhance the specular reflection of surface contaminants and defects so that they can be found more easily.
3. When cleaning a laser cutting machine protective lens, always use a clean wipe paper and an optical grade solvent to prevent damage by other contaminants. Wipe paper must be moistened with appropriate solvents, never dry use. In consideration of softness, cotton Webril wipes or applicators such as cotton balls, lens paper and cotton swabs can be used.
