The focus of the laser cutting machine should pay attention to the following three points

  1. Focusing lens material is ZnSe (zinc arsenic), which is brittle and afraid of falling; In disassembly, it is important to note that not too hard, can not collide with the hard object. On the surface, there is a membrane, which is afraid of pollution, moisture, oil and scratches. So the requirement in the work to provide the air drying, degreasing, don't directly deal with laser cutting machine with the hand focusing mirror lens, because the skin grease can produce permanent damage to the lens surface. Instead, you can operate with gloves and special sets, which are more convenient for smaller lenses, using optical tweezers or vacuum tweezers. No matter what method is used to clip the laser cutter focusing mirror, it can only be clamped along the non-optical surface, such as the grinding edge of the mirror.


    2. In general, it is necessary to check the focusing mirror of the laser cutter before and after use. Since most contaminants and surface defects are relatively small, we often need to use amplification equipment when examining the lenses. In addition to amplifying device, sometimes we need to use a more bright beam of light to illuminate optical surface, enhance the strength of specular reflection surface contaminants and defects, so that we can more easily find contaminants and defects.


    3. When cleaning a laser cutting machine focusing mirror, clean wiping paper and optical level solvents are often used to prevent damage by other pollutants. Wiping paper must be wetted with appropriate solvent and must not be used for drying. In the consideration of softness, the usable wipe paper is pure cotton Webril wipe paper or cotton ball, lens paper, and cotton swabs.
    Laser cutting machine of the focus lens this belongs to consumable, when clean after many times still short of change must be noticed when high cleanliness, guarantee the efficiency of laser cutting machine, so as not to delay the production.Collimating Lens.jpg
