Abstract

An imaging lens includes first, second, third, fourth and fifth lens elements arranged from an object side to an image side in the given order. The first lens element has a positive refractive power. The second lens element has a negative refractive power, and has an object-side surface with a concave portion, and an image-side surface with a concave portion. The third lens element has an object-side surface with a concave portion. The fourth lens element has an image-side surface with a convex portion. The fifth lens element has an object-side surface with a concave portion.

Description

technical field

[0001] The invention relates to an optical lens, in particular to a five-piece optical imaging lens and an electronic device using the lens. Background technique

[0002] In recent years, the popularity of portable electronic products such as mobile phones and digital cameras has led to the vigorous development of related technologies of image modules (mainly including optical imaging lenses, module holder units, and sensors). The trend of thinner and lighter also makes the demand for miniaturization of image modules higher and higher. With the technological progress and size To reduce the size, the length of the optical imaging lens loaded in the image module also needs to be shortened accordingly. However, in order to avoid the reduction of photographic effect and quality, good optical performance must still be taken into account when shortening the length of the optical imaging lens.
