With the continuous growth of the optical industry, the demand for lenses is also increasing. These lenses are mainly processed into various optical lenses, filters, reflectors, attenuators, optical prisms, optical lenses, etc. However, how are these optical glasses processed into precision optical products? Today, we will take a look at the specific processes of optical lens processing, mainly divided into two types: optical cold processing and optical lens polishing.
Optical cold working
1. The purpose of polishing the optical lens is to remove some rough substances from the outer surface of the optical lens and provide a preliminary model of the optical lens.
After the initial polishing is completed, the optical lens is finely polished to determine the R value and remove impurities from the surface.
After completing two polishing operations, polish the optical lens. The polishing operation can make the appearance of the optical lens delicate and smooth.
After completing the polishing operation, clean the optical lens, mainly to remove some impurities from the outside of the optical lens after polishing and polishing.
After cleaning the powder on the outside of the optical lens, start the edge grinding operation and polish the optical lens according to the required outer diameter of the lens.
After the edge grinding operation is completed, the optical lens is coated with a variety of colors, which can be coated as needed, including one or several layers of film.
After completing the coating operation, apply ink to the optical lens to prevent reflection. Simply apply black ink to the outer edge of the optical lens.
8. After the optical lenses have completed the inking work, the final step of optical cold processing is to combine and use a special adhesive to stick the two optical lenses together. The R values of the two lenses need to be opposite while maintaining the same size and outer diameter.
Polishing of optical lenses
A polishing machine and polishing powder need to be used together. During the polishing process, the polishing time and pressure of the optical lens must be determined, and some parameter values used during the polishing process must be determined. After the polishing operation is completed, the optical lens must be quickly cleaned, otherwise some polishing powder will remain on the lens and cannot be removed.
The above is the preliminary processing process for a simple optical lens. The preliminary processing for some products is the same, and these preliminary works have been done well, which plays a crucial role in the qualification rate of the product.
