Abstract

The invention discloses an optical lens, a camera device and a terminal. The optical lens comprises a first lens, a second lens, a third lens, a fourth lens and a fifth lens which are sequentially arranged from the object side to the image side along the optical axis. The first lens has positive focal power, and the object side surface of the first lens is a convex surface near the optical axis; the second lens has focal power; the third lens has focal power; the fourth lens has positive focal power, and the image side surface of the fourth lens is a convex surface near the optical axis; the fifth lens has negative focal power, and the image side surface of the fifth lens is a concave surface near the optical axis; and the optical lens satisfies the following relationship: 2<SD1 / CT12<12. According to the optical lens, through the focal power of the five-piece lens and the convex-concave design of the object side surface and the image side surface, and the met relationship: 2<SD1 / CT12<12, the size of the head of the optical lens can be effectively reduced, so that the width of the optical lens in the direction perpendicular to the optical axis is reduced, the overall size of the optical lens is compressed, the compactness of the optical lens is improved, the ghost image risk can be reduced, and the image shooting quality is ensured.

Description

technical field [0001] The present invention relates to the technical field of optical imaging, in particular to an optical lens, an imaging device and a terminal. Background technique [0002] Optical lenses for optical imaging are widely used in terminals such as smartphones, tablet computers, and cameras. Taking smart phones as an example, in order to meet the different shooting needs of users, a smart phone is usually equipped with multiple optical lenses with different characteristics and application environments. The miniaturization design also puts forward the requirement. In related technologies, the effective focal length of the optical lens is often reduced to achieve the effect of reducing the volume of the optical lens, but this method tends to increase the risk of ghost images of the optical lens and affect the quality of picture shooting.
