Problems solved by technology

[0004] However, with the vigorous development of related mold industries such as molded glass molding and injection molding, injection molded lenses have been used more and more. However, such injection molded lenses usually have burrs and gaps after gate cutting process, so Its geometric central axis is not easy to be accurately determined, and errors are pron

Embodiment Construction

[0017] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0018] see figure 1 and figure 2 , the lens 100 to be inspected in this embodiment is an embedded lens, which may be a spherical mirror or an aspherical mirror. The lens to be inspected 100 includes a main body 110 and a peripheral portion 120 surrounding the main body 110 . The main body 110 is the part of the lens that plays an optical role, and the main body 110 can be configured in a concave or convex shape according to specific needs, so as to diverge or converge light. The peripheral part 120 is annular, surrounds and connects the main part 110, and is mainly used to place and support adjacent components. The inner diameter of the main part 110 is d1 and the outer diameter is d2. The peripheral portion 120 has an inner wall 130 .

Abstract

An eyeglass eccentricity detecting system is used for conducting eccentricity detection on an eyeglass to be detected. The eyeglass comprises a main body and a peripheral part surrounding the main body; the peripheral part of the eyeglass is provided with an inner side wall. The eccentricity detecting system comprises a detecting device, a load bearing device and an eyeglass support bearing device, wherein the detecting device is used for conducting eccentricity detection on a rotating eyeglass to be detected; the load bearing device is used for bearing the eyeglass; the eyeglass support bearing device is positioned in the load bearing device, and comprises at least three spheres and an elastic element, wherein the three spheres are propped against the inner side wall of the peripheral part of the eyeglass; the eyeglass is propped by the spheres of the eyeglass support bearing device to prevent inclination during the rotation of the eyeglass; and the eyeglass support bearing device drives the eyeglass to rotate around the central axis of the main body.

Description

technical field [0001] The invention relates to an optical detection technology, in particular to a lens eccentric detection system and method. Background technique [0002] In recent years, due to the explosive growth of the digital information industry, the demand for optical lenses such as read-write lenses, digital cameras, mobile phone cameras, and optical communication components has increased significantly. When an axisymmetric optical lens is fabricated or assembled in a system, if the optical axis of the lens does not coincide with its axis of rotational symmetry, a decentering error will occur. Decentration error has a critical impact on the imaging quality of optical lenses. Therefore, the detection and evaluation of eccentricity errors of lenses and lens components is one of the important steps in the production of high-precision optical lens components. [0003] The detection method of eccentricity error usually includes mechanical measurement method and optica...
