Kunshan Noli Optical introduction: How to grind optical lenses?

Pre-processing inspection - grinding lenses - chamfering - polishing - grooving - drilling - assembly - initial adjustment - self-test - submission

First, optical cold processing

1, the optical lens is polished, the purpose is to erase some rough substances 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 polished, the R value is determined, and the surface impurities are removed.

3, after the completion of two polishing, the optical lens polishing operation, polishing operation can make the appearance of the optical lens become delicate and smooth.

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

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

6, after the grinding operation is completed, the film is coated to the optical lens, there are many colors of the film, the coating operation can be carried out according to the need, you can plate one layer of film or several layers of film.

7, after the coating operation is completed, the optical lens is inked, its role is to prevent the lens from reflecting light, as long as the black ink is applied to the outer edge of the optical lens.

8, the optical lens after the completion of the ink work, began to carry out the last step of the optical cold processing operation, that is, the use of special glue to stick the two optical lenses together, the R value of the two lenses need to be opposite, while maintaining the size and outside diameter equal.
