Abstract

The invention discloses an imaging lens and equipment including the imaging lens. An imaging lens is provided. The imaging lens includes in order from the object side to the image plane side: a first lens having a convex object side surface and having a positive refractive power; a second lens having a positive or negative refractive power; a third lens having a positive or negative refractive power Negative refractive power; The fourth lens has negative refractive power; The fifth lens has positive or negative refractive power, wherein the image side surface of the fifth lens has a concave central portion and has at least one inflection point, and the imaging lens satisfies the condition ‑0.25 ≤(Y‑y p ) / y p ≤‑0.05, where Y represents the image height of the actual chief ray, and y p Indicates the image height of the paraxial chief ray.

Description

[0001] This application claims the benefit of Korean Patent Application No. 10-2015-0037701 filed with the Korean Intellectual Property Office on March 18, 2015, the entire disclosure of which is hereby incorporated by reference. technical field [0002] The present disclosure relates to an imaging lens and an imaging device including the imaging lens. Background technique [0003] Digital still cameras or video cameras having solid-state imaging devices such as Charge Coupled Devices (CCD), Complementary Metal Oxide Semiconductors (CMOS), etc. have recently been widely spread. [0004] Imaging devices using solid-state imaging devices are also suitable for devices having a compact size, and thus are currently used in mobile devices such as smartphones. [0005] However, as the body thickness of smartphones is gradually reduced, the importance of miniaturization of imaging lens modules used in smartphones is increasing. In addition, as users' expertise with cameras continue...
