Description

TECHNICAL FIELD

[0001] The utility model relates to plano -convex lens processing technical field more specifically, it relates to a kind of stable type fine grinding and polishing auxiliary of plano -convex lens. BACKGROUND

[0002] The focal length of a single lens is the distance from the principal point to the focal point. The design wavelength of the lens is 546.1 nm (the e-line of the green mercury spectrum). Since the focal length changes with wavelength, when used for other wavelengths, its focal length also changes. In plano-convex lenses, the refractive index of the light incident from both sides is slightly different, so the focal length of both sides is also slightly different. When used, it cannot be reversed. This type of lens is used to converge parallel light or convert a point light source into parallel light and is widely used in the lenses of various optical observation instruments. During the processing of plano-convex lenses, fine grinding and polishing are required. Therefore, a stable auxiliary tool is needed during processing.

Therefore, in view of the above problems, a kind of stable type fine grinding and polishing auxiliary tool of plano-convex lens is proposed. UTILITY MODEL CONTENT
