Abstract

The invention relates to an optical lens, an image capturing module, an electronic device and a driving device. The optical lens sequentially comprises a first lens element, a second lens element, a third lens element, a fourth lens element, a fifth lens element, a sixth lens element and a diaphragm sequentially from an object side to an image side along an optical axis, wherein the first lens element has negative refractive power, the object side surface is a convex surface near the optical axis, and the image side surface is a concave surface near the optical axis; the second lens element has negative refractive power, and the image side surface is a concave surface near the optical axis; the third lens element has positive refractive power; the fourth lens element has refractive power;the fifth lens element has positive refractive power, and the object side surface is a convex surface near the optical axis; the sixth lens element has negative refractive power, and the image side surface is a convex surface near the optical axis; the sixth lens element and the fifth lens element are glued; the diaphragm is arranged on the object side of the first lens element or between the first lens element and the sixth lens element, and the object side face and / or the image side face of at least one of the first lens element to the sixth lens element are / is aspheric. The optical lens canbe balanced in the aspects of expanding the field angle range, ensuring high imaging performance and realizing miniaturization when meeting a specific relation.

Description

technical field [0001] The invention relates to the technical field of optical imaging, in particular to an optical lens, an imaging module, an electronic device and a driving device. Background technique [0002] At present, as the country's requirements for road traffic safety and car safety continue to increase, as well as the rise of surround-view cameras, ADAS (Advanced Driving Assistance System, Advanced Driver Assistance System) and driverless markets, more and more vehicle-mounted lenses are used in In the car auxiliary driving system. At the same time, people have put forward higher requirements for the imaging quality and picture comfort of vehicle-mounted lenses. Surround view camera, through the reasonable distribution of multiple ultra-wide-angle optical lenses on the body, stitches together the bird's-eye view images from all directions on the top of the car, so that the driver can see the images around the car clearly, so as to effectively avoid the bumper be...
