Cylindrical Lens cleaning and maintenance skills

First, use an air ball to blow off the floats on the Cylindrical Lens surface, especially the lenses with tiny particles and floccules on the surface. This step is necessary. But do not use compressed air on the production line, because the air will contain oil and water droplets, which will deepen the pollution of the lens. In the second step, the Cylindrical Lens is slightly cleaned with acetone. The cotton ball must be dipped in acetone and the lens must be cleaned under light and moved in a circular motion. Once the cotton swab is dirty, it must be replaced. The cleaning should be done at one time to avoid the formation of crenellations. If the lens has two coated surfaces, each surface needs to be cleaned in this way.

One side needs to be placed on a layer of clean lens paper for protection. If acetone cannot remove all the dirt, then use acid vinegar to clean it. Acid vinegar cleaning uses the dissolution of dirt to remove dirt, but it will not cause damage to the lens. Sour vinegar can be experimental grade (diluted to 50% strength), or white vinegar with 6% acetic acid for household use. The cleaning procedure is the same as that of acetone, and then acetone is used to remove the acid vinegar and dry the lens. At this time, the cotton ball should be changed frequently to completely absorb the acid and hydrate. If certain pollutants and Cylindrical Lens damage cannot be removed by cleaning, especially the film burned due to metal splash and dirt, the only way to restore good performance is to replace the Cylindrical Lens.

Five points to pay attention to when maintaining Cylindrical Lens:
　　 1. The hand cannot touch the mirror surface;
　　 2. Breath on the mirror surface or blow with air from an air compressor;
　　 3. The mirror surface cannot directly touch the surface of a hard object;
　　 4. Do not use non-lens wiping paper (stick) to wipe or wipe the lens forcefully;
　　 5. Do not press hard when disassembling the Cylindrical Lens.
