Problems solved by technology

[0002] In the current industrial lens industry, in the application of machine vision, the object distance is required to be short, and the lens volume is required to be light and compact. However, the appearance and structure of the industrial lens industry are large and inconsistent, and the versatility of integration is not high; the optical structure of the lens is distorted. The shortcomings of large size and unclear edge of the field of view have begun to fail to meet the existing market demand

Embodiment Construction

[0022] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0023] like Figure 1-2 As shown in the figure, a f35mm high-resolution low-distortion full-group mobile industrial lens of the present invention includes a lens barrel and an optical system arranged in the lens barrel. The iris C19 and the rear lens group B, the front lens group A is composed of the first biconvex lens 26 arranged in sequence and the first cemented group that is closely connected by the second biconvex lens 24 and the first biconcave lens 23; the rear lens group is composed of The lens B is composed of a second cemented group in which the second biconcave lens 15 and the third biconvex lens 14 are in close contact, and the third cemented group is composed of the fourth biconvex lens 13 and the negative crescent lens 12 in close contact.

[0024] In this embodiment, the air interval between the front lens group A and t...

Abstract

A f35mm high-resolution low-distortion complete set mobile industrial lens of the present invention comprises a lens cone and an optical system arranged in the lens cone, and the optical system comprises a front-set lens A, a variable diaphragm C and a back-set lens B which are arranged orderly along a light ray incident direction. The front-set lens A is composed of a first biconvex lens and a first gluing set formed by the tight connection of a second biconvex lens and a first biconcave lens which are arranged orderly, and the back-set lens B is composed of a second gluing set formed by thetight connection of a second biconcave lens and a third biconvex lens and a third gluing set formed by the tight connection of a fourth biconvex lens and a negative crescent lens which are arranged orderly. The f35mm high-resolution low-distortion complete set mobile industrial lens is light and compact in structure, enables the integration versatility to be improved, satisfies the requirement that the industrial lens is small in distortion, and has the high resolution.

Description

Technical field: [0001] The invention relates to an f35mm high-resolution and low-distortion full-group mobile industrial lens. Background technique: [0002] In the current industrial lens industry, in the application of machine vision, the object distance is required to be short, and the size of the lens is required to be light and compact. However, the appearance and structure of the industrial lens industry are currently large and non-uniform, and the integration versatility is not high; the optical structure of the lens is distorted. The disadvantages of large size and unclear edge of the field of view have begun to fail to meet the existing market demand. Invention content: [0003] The purpose of the present invention is to provide a f35mm high-resolution and low-distortion full-group mobile industrial lens in view of the above shortcomings, the lens structure is light and compact, and the integration versatility is improved. [0004] In order to achieve the above ...
