Optical lenses differ from ordinary lenses in that they have a high degree of transparency, a high degree of uniformity in physical and chemical properties, and specific and very precise optical constants, which cannot be replaced by ordinary lenses.
The processing of optical lenses is also very complex, including optical cold processing and polishing of glass lenses.First of all, to erase some rough substances on the outer surface of the optical lens,
it is necessary to polish the optical lens first, and then carry out a fine polishing; then there is the polishing of the optical lens, in this step the operator has to cooperate with the use of polishing machine and polishing powder,
the polishing operation can make the appearance of the optical lens become delicate and smooth, there is also a cleaning after the polishing, after the cleaning according to the outer diameter of the required lenses will be optical lens After cleaning, the optical lenses are polished according to the outer diameter of the desired lenses.
The optical lenses are then coated, either with one or more layers, in different colors.The outer edges of the optical lenses are then inked, the purpose of which is to prevent reflection of the lenses.
Once the inking of the optical lens is complete, the final step of the optical cold working process is the joining of the two optical lenses, which are glued together using a specific adhesive, with the R-values of the two lenses reversed, while keeping the size and outer diameter equal.
