Kunshan Noli Optical introduction: optical lens cold processing technology

1, the optical lens is polished, the purpose is to erase the rough material on the outer surface of the optical lens, and establish a preliminary model on the optical lens.

2, after the initial grinding is completed, the optical lens is polished, the R value is determined, and the surface impurities are removed.

3. After finishing polishing twice, polish the optical lens. The polishing operation gives the optical lens a fine and smooth appearance.

4, clean the optical lens after polishing, mainly polishing and polishing to remove impurities outside the optical lens.

5. After the powder on the outside of the optical lens is cleaned, the edging operation begins and the optical lens is polished to the required lens diameter.

6, after the grinding operation is completed, the optical lens can be coated according to the need for coating operation, plating a film or multilayer film.

7, after finishing the coating work, the ink is applied to the optical lens. As long as the outer edge of the optical lens is coated with black ink, it has the effect of preventing the lens from reflecting light.

8, after the optical lens is inked, the final optical cold processing operation begins. It's a combination. A special glue is used to bond the two optical lenses together, and the two lenses need to have opposite R-values while keeping the size and outside diameter equal.
