Abstract

The invention discloses an optical imaging lens and an electronic device applying the optical imaging lens. The optical imaging lens sequentially comprises a first lens, a second lens, a third lens, a fourth lens, a fifth lens and a sixth lens from an objective side to an image side along an optical axis, wherein the first lens has a negative refractive index; an image side face of the second lens is provided with a convex face portion located in an area nearby a circumference; an objective side face of the third lens is provided with a convex face portion located in an area nearby the circumference; an image side face of the fifth lens is provided with a convex face portion located in an area nearby the optical axis; and an objective side face of the sixth lens is provided with a concave face portion located in an area nearby the circumference. The number of lens with a refractive index of the optical imaging lens is only six. The electronic device comprises a casing and an image module installed in the casing, wherein the image module comprises the optical imaging lens, a lens cone, a module rear base unit, a substrate and an image sensor. The optical imaging lens and the electronic device applying the optical imaging lens enable a lens to have predetermined optical performance.

Description

technical field [0001] The present invention generally relates to an optical imaging lens and an electronic device including the optical imaging lens. Specifically, the present invention particularly refers to an optical imaging lens with reduced system length, and an electronic device using the optical imaging lens. Background technique [0002] In recent years, with the popularization of mobile communication devices and digital cameras, the specifications of consumer electronics products are changing with each passing day. Good optical performance is also necessary to take into account. Therefore, the specifications of key components of electronic products such as optical lenses must continue to improve in order to meet the needs of consumers. The most important characteristics of optical lenses are nothing more than image quality and size. [0003] U.S. Patent US7580205 discloses a six-piece wide-angle optical lens. In order to achieve better imaging quality, more lens...
