Laser cutting machine in the lens installation and cleaning process, any one sticky, and even nails printed oil droplets, will make the lens absorption rate increased, reducing the service life. Therefore, the following precautions must be taken:
1, do not use bare fingers to install the lens. Should wear finger or rubber gloves.
2. Do not use sharp instruments to avoid scratching the lens surface.
3, can not touch the film when taking the lens, but holding the edge of the lens.
4, the lens should be placed in a dry, clean place to detect and clean. There should be several layers of cleaning tissues on the surface of a good table and several cleaning lens tissue papers.
5. Users should avoid talking over the lens and keep food, beverages and other potential contaminants away from the work environment.
In the process of cleaning lenses, a relatively low risk method should be used. The following steps are set up for this purpose and should be used by users.
First, use a blower to blow off the float on the surface of the original, especially the lens with tiny particles and flocs on the surface. This step is necessary. But do not use compressed air on the production line, because these air will contain oil mist and water droplets, which will increase the pollution of the lens.
In the second step, the lens was slightly cleaned using pure acetone. This grade of acetone is almost anhydrous, which reduces the possibility of lens contamination. (China Cutting Machine Trading Network)
The cotton ball must be cleaned with acetone in the light and the ring moved. Once the swab is dirty, it must be replaced. Cleaning should be done at one time to avoid ripples.
If the lens has two coated surfaces, such as lenses, each side needs to be cleaned in this way. The first side needs to be put on a layer of clean lens paper for protection.
If acetone can't remove all the dirt, then wash it with vinegar. In vinegar cleaning, the dirt is removed by dissolving the dirt, but it does not damage the optical lens. The vinegar can be of experimental grade (diluted to 50% strength) or white vinegar with 6% acetic acid for home use. The procedure for cleaning is the same as for acetone, and then acetone is used to remove the vinegar and dry the lens. At this time, the cotton balls must be replaced frequently to completely remove the acid and hydrate. Until it is clean.
When the contaminants and lens damage cannot be removed by cleaning, especially if the film is burned due to metal splashing and dirt, the only way to restore good performance is to replace the lens.
