Example Embodiment

[0027] In order to make the above-mentioned features and advantages of the present invention more comprehensible, the following specific examples are given in conjunction with the drawings, and detailed descriptions are made as follows.

[0028] Such as Figure 1~2 As shown, a high-resolution whole group of mobile industrial camera lenses includes a front group A with negative refractive power, a variable diaphragm C, and a rear rear with positive refractive power that are sequentially arranged along the incident direction of light from left to right. Group B, the front group A is composed of a positive crescent lens A-1, a biconvex lens A-2 and a biconcave lens A-3, and the biconvex lens A-2 is in close contact with the biconcave lens A-3 Is the first cemented group, the rear group B consists of a biconcave lens B-1, a biconvex lens B-2, a biconvex lens B-3, and a negative crescent lens B-4. The biconcave lens B -1 and the biconvex lens B-2 are closely connected to form the sec...

Abstract

The invention relates to a high-resolution whole-set mobile industrial photographing camera lens. The high-resolution whole-set mobile industrial photographing camera lens comprises a front set A with negative focal power, a variable light diaphragm C and a rear set B with positive focal power, which are arranged in sequence along light from a left incident direction to a right incident direction, wherein the front set A is composed of a positive crescent-shaped lens A-1, a double-convex lens A-2 and a double-concave lens A-3; the double-convex lens A-2 and the double-concave lens A-3 are tightly connected to form a first gluing set; the rear set B is composed of a double-concave lens B-1, a double-convex lens B-2, a double-convex lens B-3 and a negative crescent-shaped lens B-4; the double-concave lens B-1 and the double-convex lens B-2 are tightly connected to form a second gluing set; the double-convex lens B-3 and the negative crescent-shaped lens B-4 are tightly connected to form a third gluing set. The high-resolution whole-set mobile industrial photographing camera lens provided by the invention is reasonable in optical structure design, and has high resolution, accurate and stable actions including focusing and the like and has a good hand feeling.

Description

technical field [0001] The invention relates to a high-resolution whole group mobile industrial camera lens. Background technique [0002] The rapid development of science and technology and the gradual improvement of people's safety awareness have promoted the continuous progress of the security market. Nowadays, with the continuous maturity of advanced video compression coding technology, the rapid development of IP-based network transmission and the application of digital zoom technology, a series of high-definition cameras with 3 million and 5 million pixels have been launched on the market. However, in the process of network transmission and digital zooming, the clarity (resolution) of the video will decrease to a certain extent, but at the same time, people's requirements for image resolution are getting higher and higher, so the front-end The resolution of the lens has higher requirements. High-resolution industrial camera lenses have the characteristics of high res...
