The birth and development of optical glass in China
The series of optical glass products was established in the early 20th century by the famous German optometrist E.Abbe and the chemist O.Schott. In the First World War, due to the German embargo, the United States was forced to solve the manufacturing of optical glass itself, and wrote a book on optical glass manufacturing after the war, but it was an internal work.

The goniometer measures the difference between prism and Angle block tower
Tower difference, also called edge difference, is an important parameter to define whether the prism machining is qualified. The most commonly used definition is that the tower difference is equal to the parallel difference between the edge of a prism and its opposite working face.

Polishing process of optical lens
After the optical lens is finely ground by the grinding liquid, there is a crack layer of about 2-3m thickness on the surface, and the method to eliminate this crack layer is polishing. The mechanism of polishing and grinding is the same, only the tool material used is different from the slurry.

UV mirror, polarizer, filter function is different from it
For shooting, no filters should be the best. Especially when facing the light source, the glare brought by the UV mirror will definitely affect the picture. The role of the coating is to minimize the generation of glare. Multi-layer coating UV is plated 6-8 layers on each side of the lens to ensure that there is more than 95% light transmission.

The present situation and technological development of optical glass processing equipment
More and more precision instruments are used in the new technology of the combination of optomechanics, which promotes the increasingly strict requirements of multi-function, high performance and low cost, and promotes the development of traditional optical glass processing equipment, production technology and processing technology. This change has pushed the development of optical mechanics technology in two different directions.
