Abstract

The invention provides an optical lens and imaging equipment, and belongs to the technical field of optical imaging. The optical lens comprises seven lenses which sequentially comprise a first lens with negative focal power, a second lens with negative focal power, a third lens with with positive focal power, a diaphragm, a fourth lens, a fifth lens, a sixth lens and a seventh lens from an object side to an imaging surface along an optical axis, wherein the fourth lens has positive focal power; the fifth lens has focal power; the sixth lens has negative focal power; the seventh lens has positive focal power; wherein the sixth lens and the seventh lens are glued into a glued body, and the optical centers of all the lenses are located on the same straight line. The optical lens meets the conditional expression that TTL/D is larger than 2.18 and smaller than 2.34, TTL represents the total optical length of the optical lens, D represents the maximum optical aperture of the optical lens, and the optical lens has the advantages of being small in size, high in resolution and large in aperture. The imaging equipment includes the optical lens and an imaging element that converts an optical image into an electrical signal.

Description

technical field [0001] The invention relates to the technical field of optical imaging, in particular to an optical lens and imaging equipment. Background technique [0002] As ADAS (Advanced Driving Assistant System, Advanced Driver Assistance System) is more and more used in automobiles, the application range of vehicle cameras is becoming wider and wider, and the demand for use is also increasing. Optical lenses are used as vehicle cameras An important part of it, it is also constantly innovating and developing in the direction of high pixels. [0003] The current conventional vehicle lens has a low resolution, and it is difficult to match the current high-pixel, high-resolution 8M chip, which cannot meet the needs of the market. Contents of the invention [0004] Based on this, the present invention provides an optical lens and an imaging device, which can overcome the above-mentioned defects of the vehicle-mounted lens in the prior art, so as to meet the design requi...
