Background

The manufacture and adjustment of optical lenses is a very delicate process. With the increase of the optical design level, higher resolution is obtained in order to achieve high-quality imaging performance. Optical glass is after production, and the workman need carry out regularly selective examination to the product of production, prevents to appear the defective goods in batches, and in the inspection process, light all can take place to launch on the interface of medium, and optical lens is indispensable component part in most optical system, and the lens number is more in the light path, and the loss that light arouses owing to launch is just bigger. Therefore, the surface of the optical lens is often coated with an antireflection film. The refractive index of the antireflection film is generally about 1.5, while theoretically the refractive index of the antireflection film is required to be about 1.22, so that the number of the antireflection films needs to be increased to reduce the refractive index. Generally, the antireflection film of a high-transmittance optical lens with good performance can reach dozens of layers or even hundreds of layers, so the traditional high-transmittance optical lens has quite complicated preparation process and relatively high cost, and the lens, the prism, the corneal contact lens, the artificial lens and the like are utilized to correct the vision, eliminate the asthenopia and protect or treat the eyes. In addition, there are various protective glasses, cosmetic glasses, and visual aids for correcting low vision, all of which are thin lenses with a fixed degree of reciprocal of the focal length (m) of the lenses. The lenses are classified into spherical lenses and cylindrical lenses. The curved surface of the spherical lens is a part of the spherical surface, and is classified into a convex spherical lens or a concave spherical lens according to the convergence or separation of parallel light rays. The convex spherical lens is used for correcting hyperopia, presbyopia or aphakia, the concave spherical lens is used for correcting myopia, the curved surface of the cylindrical lens is a part of a cylinder, the axis of the cylindrical lens is parallel to the cylinder, no refractive power exists in the axial direction, the refractive power is maximum in the direction vertical to the axis, and the convex cylindrical lens or the concave cylindrical lens is used for correcting hyperopia or myopic astigmatism respectively. The prism is composed of two lenses which are not parallel and are intersected to form an angle, and the prism is used for treating certain eye muscle diseases due to the characteristic that the object image is shifted towards the tip. The existing optical lens surface detection device places optical glass on a desktop, but due to the transparent characteristic of the optical glass, the optical lens surface detection device is inconvenient to fix, difficult to observe at multiple angles and prone to leakage.
