Portable electronic device and optical imaging lens thereof

Abstract

The invention relates to a portable electronic device and an optical imaging lens thereof. The optical imaging lens comprises five lenses. The image side surface of the first lens is provided with a convex part arranged in the area close to the periphery. The image side surface of the second lens is provided with a concave part arranged in the area close to the periphery. The image side surface of the third lens is provided with a convex part arranged in the area close to the periphery. The image side surface of the third lens is provided with a concave part arranged in the area close to an optical axis and a convex part arranged in the area close to the periphery. The fourth lens has a positive refraction rate. The image side surface of the fourth lens is provided with a concave part arranged in the area close to the optical axis and a convex part arranged in the area close to the periphery. The image side surface of the fifth lens is provided with a concave part arranged in the area close to the optical axis. The following relation is satisfied: (T1+T2) / G23>=3.65. The portable electronic device comprises a housing, an image module comprising the optical imaging lens, a lens barrel, a module backseat unit and an image sensor. The portable electronic device and the optical imaging lens thereof are good in imaging quality.

Description

technical field [0001] The present invention is related to a portable electronic device and its optical imaging lens, and especially related to a portable electronic device using a five-piece lens and its optical imaging lens. Background technique [0002] The specifications of consumer electronic products are changing with each passing day, and the pursuit of thinness and shortness has not slowed down. Therefore, the specifications of key components of electronic products such as optical lenses must continue to be improved in order to meet the needs of consumers. Among them, the most important characteristics of optical lenses It's nothing more than image quality and volume. In terms of the five-element lens structure, the distance on the optical axis from the object side of the first lens to the imaging surface is relatively large in the past, which is not conducive to the thinning of mobile phones and digital cameras. Therefore, it is extremely necessary to develop a lens...

In terms of the five-element lens structure, the distance on the optical axis from the object side of the first lens to the imaging surface is relatively large in the past, which is not conducive to the thinning of mobile phones and digital cameras. Therefore, it is extremely necessary to develop a lens with good image quality and shortened lens length lens
