Briefly introduce the advantages of optical elements made of optical glass

Optical glass is the foundation and main component of the optoelectronic technology industry. Optical glass lens molding technology is a high-precision optical component processing technology. It is to put the softened glass into high-precision molds, and directly press the required optical components at one time under the conditions of heating, pressure and oxygen free. This technology has become one of the most advanced optical element manufacturing technologies in the world. What are the advantages of optical glass in manufacturing optical components?

Optical glass molding method for manufacturing optical elements has the following advantages:

1. It does not need traditional processes such as rough grinding, fine grinding, polishing, edge grinding and base setting, so that the parts can reach high dimensional accuracy, surface accuracy and surface roughness;

2. Optical parts and device reference parts can be made into a whole;

3. Capable of molding small aspheric lens array;

4. It can easily and economically realize the mass production of precision aspheric optical parts;

5. As long as the technical parameters such as temperature and pressure in the molding process are accurately controlled, the dimensional accuracy and repeatability of the molded optical parts can be ensured.
