High-resolution prime lens and camera

Abstract

The invention discloses a high-resolution prime lens and a camera, wherein the high-resolution prime lens comprises a mechanical device and an optical system mounted in the mechanical device, and the optical system is sequentially provided with a front lens group, a middle lens group, a diaphragm and a rear focusing group from an image space to an object space; the front lens group comprises a first lens with positive focal power, a second lens with negative focal power and a third lens with negative focal power; the middle lens group comprises a fourth lens with positive focal power and a fifth lens with positive focal power; and the rear focusing group comprises a sixth lens with positive focal power, a seventh lens with negative focal power, an eighth lens with positive focal power, a ninth lens with positive focal power, a tenth lens with negative focal power and an eleventh lens with positive focal power; by adopting the high-resolution prime lens, the matching of a camera with a larger target surface and a higher resolution is facilitated.

Description

technical field [0001] The invention relates to the field of lens technology, in particular to a high-resolution fixed-focus lens and a camera. Background technique [0002] With the development of industrial automation, industrial lenses are widely used in the field of machine vision inspection, such as workpiece measurement and judgment, defect detection, food packaging, intelligent logistics, medical judgment and so on. At present, most industrial lenses on the market can only match cameras with 2 / 3-inch target surface and 5 million pixels and 1.1-inch target surface and 12 million pixels. With the continuous improvement of detection accuracy requirements and high-resolution With the wide application of high-resolution cameras, there is an increasing demand for industrial lenses that can match larger target areas and higher-resolution cameras, so a high-resolution fixed-focus lens with excellent performance that can meet the above requirements is required.
