Processing of optical lenses

Optical cold working

1. The purpose of grinding the optical lens is to erase some rough materials on the outer surface of the optical lens, so that the optical lens has a preliminary model.

2. After the initial grinding is completed, the optical lens is finely ground, the R value is determined, and the impurities on the surface are removed.

3. After two grindings, polish the optical lens. The polishing operation can make the appearance of the optical lens delicate and smooth.

4. After the polishing operation is completed, the optical lens is cleaned, mainly to remove some impurities outside the optical lens after grinding and polishing.

5. After cleaning the powder on the outside of the optical lens, start the edging operation, and grind the optical lens according to the outer diameter of the required lens.

6. After the edging operation is completed, the optical lens is coated with a film. There are many colors of the film. The coating operation can be carried out according to the needs, and one or several layers of film can be coated.

7. After the coating operation is completed, apply ink to the optical lens. Its function is to prevent the lens from reflecting, as long as the black ink is applied to the outer edge of the optical lens.

8. After the optical lens is inked, start the last step of optical cold processing, that is, to combine, use special glue to stick the two optical lenses together. The R values ​​of the two lenses need to be opposite, while maintaining the size and size. Outer diameters are equal.

Polishing of glass lenses

It is necessary to use a polishing machine and polishing powder together. During the polishing process, the polishing time and polishing pressure, etc. some parameters used in the polishing process must be determined. After the polishing operation is completed, the optical lens should be quickly Cleaning, otherwise some polishing powder will remain on the lens and cannot be removed.
