Description
Technical Field
The invention relates to the technical field of optical device detection, in particular to an aspheric lens surface type detection system.
Background
Aspherical lenses are lenses which are not spherical in curvature but have a lens edge portion "" chipped "" off a small amount and a planar cross-section. When light is incident on the aspherical mirror surface, the light can be focused on a point, namely the film plane, so that various aberrations can be eliminated. For example, the glare phenomenon is more serious when the spherical mirror uses a large aperture than when the spherical mirror uses a small aperture, but the glare condition can be greatly reduced if the aspherical mirror is added; further, for example, the image is distorted (pincushion or barrel-shaped) due to the fact that the light in the lens is not properly refracted, and in the case of a zoom lens, the short focal length is generally barrel-shaped distortion, and the zooming is pincushion-shaped distortion when the lens is zoomed to the long focal length, and if an aspherical lens is used, the aberration in this respect can be improved.
The aspherical mirror technology is used to produce lens with large aperture, high zooming factor, wide angle and telephoto end, and this results in high image quality and reduced lens size. Currently, there are many lens manufacturers that use aspheric lenses for lenses with partial focal length under the flag, so that portable zoom cameras (e.g. 28 to 90mm, 38 to 105mm, etc.) use aspheric lens designs to improve image quality.
The difficulty in manufacturing the aspherical mirror lies in the design of the geometric dimension and the precise control of the geometric dimension, so that the aspherical mirror is particularly important for detecting the surface type of the aspherical mirror and has low manual detection efficiency.
