Abstract

The present application discloses an imaging lens system, which sequentially includes a first lens, a second lens, a third lens, a fourth lens and a fifth lens along the optical axis from the object side to the image side. Among them, the first lens has positive power; the second lens has negative power, and its image side is concave; the third lens has positive power, and its object side is concave; the fourth lens has power, and its object side is concave. It is a convex surface; the fifth lens has positive refractive power, and its image side is concave; and the distance TTL on the optical axis from the object side of the first lens to the imaging surface of the imaging lens system is equal to the length of the effective pixel area diagonal on the imaging surface Half of ImgH satisfies TTL / ImgH<1.5.

Description

technical field [0001] The present application relates to an imaging lens system, and more particularly, the present application relates to an imaging lens system including five lenses. Background technique [0002] In recent years, with the continuous development of portable electronic products such as smart phones, camera lens systems applied to smart phones are facing the challenges of high pixel, low cost, and miniaturization. Especially for the front lens of mobile phones, under the condition of strict cost control, the five-piece front lens still occupies the mainstream position in the current market. [0003] At present, the mobile phone market is increasingly pursuing high-resolution and thinner camera lenses, and large image areas and short system lengths have become the main factors considered by major mobile phone manufacturers. A large image area means higher image resolution, and a short system length means that the lens can be made smaller and thinner, which c...
