Abstract

The invention discloses an optical lens, a camera module, electronic equipment and an automobile. The optical lens comprises a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens, a seventh lens, an eighth lens, a ninth lens, a tenth lens and an eleventh lens which are sequentially arranged from an object side to an image side along an optical axis; the first lens has negative refractive power, the object-side surface and the image-side surface of the first lens are convex and concave in a paraxial region, the second lens has negative refractive power, the image-side surface of the second lens is concave in a paraxial region, the third lens, the fourth lens and the fifth lens have refractive power, the sixth lens has positive refractive power, the object-side surface of the sixth lens is convex in a paraxial region, the seventh lens, the eighth lens, the ninth lens and the tenth lens have refractive power, the object-side surface of the seventh lens and a paraxial region thereof are convex, the object-side surface of the tenth lens is concave in a paraxial region thereof, and the eleventh lens has positive refractive power. According to the optical lens, the camera module, the electronic equipment and the automobile, a large-image-plane imaging effect can be realized on the basis of considering the miniaturization design requirement.

Description

technical field [0001] The present application relates to the technical field of optical imaging, in particular to an optical lens, a camera module, electronic equipment and an automobile. Background technique [0002] In recent years, with the development of the automotive industry, the technical requirements for automotive cameras such as ADAS (Advanced Driver Assistant System), driving recorder, and reversing camera are getting higher and higher. Taking the ADAS lens as an example, the ADAS lens can accurately and real-time capture road surface information (such as detecting objects, detecting light sources, detecting road signs, etc.) Field of view, used in monitoring and security, can also clearly record detailed information, etc., providing corresponding technical support and application guarantee in various aspects of practical application, so the market demand for ADAS lenses is also increasing day by day. However, the pixels of the ADAS lens in the related art are ...
