Description

Technical Field

[0001] The utility model relates to the technical field of lens processing and fixing, in particular to a lens processing and fixing device. Background Art

[0002] A lens is an optical element made of transparent material (such as glass, crystal, etc.). Convex lens: thick in the middle and thin at the edges, there are three types: biconvex, plano-convex, and concave-convex; concave lens: thin in the middle and thick at the edges, there are three types: biconcave, plano-concave, and convex-concave. Lenses play an important role in astronomy, military, transportation, medicine, art and other fields.

[0003] During the production and processing, the lens needs to be fixed with the help of a fixing device to ensure the stability of subsequent processing, and then the lens is processed in various steps with the help of external equipment.
