Portable electronic device and optical imaging camera lens thereof

Abstract

The invention provides a portable electronic device and an optical imaging camera lens thereof. The optical imaging camera lens sequentially comprises a first lens, a second lens, a third lens, a fourth lens, and a fifth lens from the object side to the image side. The optical imaging camera lens only comprises the five lenses with the refractive index. ALT represents the thickness sum of the five lenses on the optical axis, G45 represents an air gap width between the fourth lens and the fifth lens on the optical axis, and ALT / G45 is no more than 6.0. The electronic device comprises a shell and an image module which is installed in the shell. The image module comprises the above mentioned optical imaging camera lens, a lens cone, a module backseat unit, a substrate, and an image sensor. The portable electronic device and the optical imaging camera lens thereof are used for optical photography. By controlling the arrangement of concave-convex curved surfaces of all the lenses, the length of the camera lens is reduced on the condition of maintaining the good optical property.

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. However, the design of an optical lens is not simply to scale down a lens with better image quality to produce an optical lens with both image quality and miniaturization. The design process also involves material properties and assembly yield. And other practical problems on the production side. [0...
