Description

Technical Field

[0002] A cylindrical lens is a cylindrical lens with a cross-section consisting of two circular arcs or one circular arc and a straight line. It comes in several types, including biconvex, biconcave, plano-convex, plano-concave, and crescent-shaped. A cylindrical lens has a focal line parallel to the cylindrical surface; the distance between the focal line and the cylindrical surface depends on the radius of curvature of the lens and the refractive index of the glass. Processing equipment for cylindrical lenses often employs multi-axial devices working together to complete the surface machining.

The hydraulic lifting control is a mature existing technology, which will not be described in detail here.

[0037] Example 2: After processing, the lens holder 21 and the cylindrical lens are removed together. The glue is then removed to separate the two. This technology is used in the processing of existing optical devices.
