Embodiment Construction

[0100] The present invention will be further described in conjunction with the accompanying drawings and specific embodiments.

[0101] Before the present invention is described in detail, it should be noted that in the following description, similar components are denoted by the same numerals.

[0102] The term "a lens has positive refractive power (or negative refractive power)" in this specification means that the lens has positive refractive power (or negative refractive power) in the area near the optical axis. "The object side (or image side) of a lens has a convex surface (or concave surface) located in a certain area" means that the area is closer to the direction parallel to the optical axis than the area immediately outside the area in the radial direction. "Outwardly convex" (or "inwardly concave"), with figure 1 For example, where I is the optical axis and the lens is radially symmetrical to each other with the optical axis I as the axis of symmetry, the object si...

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. [0003] According to US Patent Publication Nos. 20110176049, 2011031696...
