Abstract

The invention discloses a high-resolution ultralow-distortion optical system and a lens, and the optical system comprises a first lens which has negative focal power; the second lens has positive focal power, and the second lens and the first lens are arranged at an interval; the third lens has negative focal power, and the third lens and the second lens are arranged at an interval; the fourth lens has negative focal power; the fifth lens has positive focal power; the sixth lens has positive focal power; the seventh lens has negative focal power; a diaphragm; the eighth lens has negative focal power, and the eighth lens and the diaphragm are arranged at an interval; the ninth lens has positive focal power; the tenth lens has positive focal power; an eleventh lens having positive focal power; the twelfth lens has positive focal power; the thirteenth lens has negative focal power; and the photosensitive chip is used for capturing the imaging signal and forming an image. By arranging lens combinations of different structures and reasonably distributing the focal power of each lens, low distortion and high relative illumination of the optical system are realized while high-definition resolution is obtained.

Description

technical field [0001] The invention relates to the technical field of optical lenses, in particular to a high-resolution ultra-low distortion optical system and a lens. Background technique [0002] Industrial lenses have the characteristics of high resolution and good stability, and are widely used in machine vision fields such as defect detection, dimension measurement, and security monitoring. In order to ensure a good imaging effect, the specifications and performance requirements of this type of lens are very high. It is required to meet high-definition resolution capabilities, small picture distortion, and relatively high relative illuminance to ensure the uniformity of image surface illuminance. With the improvement of imaging chip research and development and production capacity, the corresponding requirements for lenses are also getting higher and higher. The existing lenses on the market are increasingly unable to match the image quality requirements of the new ge...
