Abstract

An optical lens, a camera module and electronic equipment are provided, the optical lens includes a first lens, a second lens, a third lens, a fourth lens, a fifth lens and a sixth lens which are sequentially arranged from an object side to an image side along an optical axis, the first lens has positive refractive power, an object side surface and an image side surface of the first lens are respectively a convex surface and a concave surface at the optical axis, and the second lens has refractive power, an object side surface and an image side surface of the second lens are respectively a convex surface and a concave surface at the optical axis, the third lens has refractive power, the fourth lens with positive refractive power has a concave object-side surface and a convex image-side surface at paraxial regions thereof, the fifth lens has negative refractive power, and the sixth lens with refractive power has a convex object-side surface and a concave image-side surface at paraxial regions thereof. The optical lens satisfies the following relation: FNO / TTL < 0.6 mm. By adopting the embodiment of the invention, the miniaturization design of the optical lens can be realized, and the clear aperture of the optical lens can be increased, so that the optical lens can have larger luminous flux, and the imaging definition is improved.

Description

technical field [0001] The invention relates to the technical field of optical imaging, in particular to an optical lens, a camera module and electronic equipment. Background technique [0002] In recent years, with the advancement of the technology industry, imaging technology has continued to develop, and optical lenses for optical imaging have been widely used in electronic devices such as smartphones, tablet computers, and cameras. Taking smart phones as an example, in order to improve the shooting effect and achieve high-quality, high-resolution, and high-definition pictures captured by micro-camera components, it is often necessary to equip a smart phone with a camera capable of shooting high-quality images. However, under the development trend of miniaturization and thinning of smart phones, correspondingly, the camera also needs to satisfy the miniature design. However, the camera with the miniature design has a small aperture and insufficient luminous flux, which af...
