Embodiment Construction

[0021] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0022] Such as figure 1 and 2 As shown, a large image surface, high resolution and low distortion optical lens of the present invention, from left to right along the light incident direction, the optical system is composed of four parts: the first lens group 1, the diaphragm 2, the second lens group 3 and the imaging surface 4, wherein the refractive power of the first lens group 1 is positive, and the refractive power of the second lens group 3 is positive.

[0023] The first lens group 1 includes six lenses from left to right along the incident direction of light: biconvex lens one 11, convex-concave lens two 12, biconcave lens three 13, concave-convex len...

Abstract

The invention relates to a large-image-plane, high-resolution and low-distortion optical lens. An optical system is composed of a first lens assembly, a diaphragm, a second lens assembly and an imaging plane from left to right in the light incidence direction. The focal power of the first lens assembly is positive, and the focal power of the second lens assembly is positive. Spherical design is used in the optical lens, the processing property is good, and the material cost is low. The large-image-plane, high-resolution and low-distortion optical lens can be widely applied to the fields of industrial measuring detection, intelligent traffics and the like.

Description

technical field [0001] The invention relates to an optical imaging system, in particular to an optical lens with large image plane, high resolution and low distortion. This lens can be widely used in opto-mechanical-electrical integration fields such as intelligent transportation, industrial inspection, motion capture, optical imaging, etc. Background technique [0002] With the continuous development of modern optical technology, in the fields of industrial inspection, intelligent transportation, etc., in order to obtain a larger imaging range and higher imaging resolution, camera manufacturers are increasing the size of optical imaging chips. The common large size Imaging components include 1 / 1.8″, 2 / 3″, 3 / 4″, etc. In recent years, 1 / 1″ and 4 / 3″ have appeared on the market. But if the designed imaging surface of the optical lens does not reach the size of a large chip size, it will cause a certain degree of vignetting. The current optical lens with a focal length of f=12m...
