How to choose fiber laser cutting machine lens?
Protective lenses, as the name suggests, is used to prevent dust and slag splash, protect the focus lens.-fiber laser cutting machine
Other than those used in fiber laser cutting machines.
they are also necessary for other laser equipment including laser marking,laser welding and laser engraving . Visible, the application of protective lenses market is very large.
Select the laser cutting machine lens protection three steps-fiber laser cutting machine
1) Overall dimensions match, this is easy to understand;
2) Materials, according to different laser power, consider the use of cost.you can choose K9, quartz, in the practical application process,
professional manufacturers divide into two types of material into multiple levels.customers can choose the appropriate specifications according to actual needs.
3)Coating, laser antireflection film, according to the use of different coating technology parameters.
Although the protective lens of fiber laser cutting machine is vulnerable parts,
in order to improve its utilization rate and reduce the production cost.
You can clean the lens by regular cleaning, to achieve the purpose of recycling,
Here are three cleaning steps summarized by XT LASER:
1)Protective lens material is ZnS (zinc arsenic), more brittle, afraid of falling.-fiber laser cutting machine
Pay attention to when dismantling: can not be too hard, can not collide with hard object.
Anti-reflective film on the surface, afraid of pollution, afraid of wet, afraid of oily, afraid of scratch.
It is required in the work to provide dry, to the oil air, do not directly handle laser cutting machine lens protection lenses, because the skin will have a permanent fat on the lens surface damage.
Instead, you can work with gloves and its special kit, and for smaller lenses, optical tweezers or vacuum tweezers are more convenient.
No matter what method to clip the laser cutting machine to protect the lens,must follow the non optical surface clamping, such as the frosted edges on the mirror plaque.
2)Under normal circumstances, before and after cleaning are required to check the laser cutting machine to protect the lens.
Because most of the contaminants and surface defects are relatively small in size, we often need to magnify the equipment when examining the lenses.
In addition to enlarging the equipment, sometimes we need to illuminate the optical surface with a brighter beam of light, enhancing the specular reflection of surface contaminants and defects, making it easier to spot contaminants and defects.
3)When cleaning a laser cutting machine to protect the lens, often use a clean wipe paper and optical grade solvent to prevent damage by other pollutants.
Use wet wipe the paper , do not dry to use.
In the softness of the consideration, the available wipe paper is cotton Webril wipe paper or cotton ball, lens paper, and cotton applicator applicator.
