Optical imaging lens and electronic device applying optical imaging lens

Abstract

The invention relates to 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 and a fifth lens from an objective side to an image side, wherein the lenses are all provided with an objective side face facing to the objective side and an image side face facing to the image side, the first lens has a negative refractive index, and the second lens has a positive refractive index and is provided with a convex face portion located in an area nearby a circumference; the objective side face of the third lens is provided with a concave face portion located in an area nearby the circumference, and the image side face is provided with a convex face portion located in an area nearby the circumference; and the image side face of the fourth lens is provided with a convex face portion located in an area nearby an optical axis, and the objective side face of the fifth lens is provided with a concave face portion located in an area nearby the optical axis. The electronic device comprises a casing and an image module, wherein the image module comprises the optical imaging lens, a lens cone, a module rear base unit and an image sensor. The lens provided by the invention has good optical performance under the condition of length contraction.

Description

technical field [0001] The invention relates to an optical lens, in particular to an optical imaging lens and an electronic device using the optical imaging lens. Background technique [0002] In recent years, the popularity of portable electronic products such as mobile phones and digital cameras has led to the vigorous development of imaging module related technologies. The imaging module mainly includes optical imaging lenses, module holder units and sensors, etc. Components, and the thin and light trend of mobile phones and digital cameras has also increased the miniaturization requirements of image modules. -Oxide Semiconductor (CMOS for short) technology advancement and size reduction, the optical imaging lens loaded in the image module also needs to be shortened in length accordingly, but in order to avoid the decline in photographic effect and quality, when shortening the length of the optical imaging lens Good optics still have to be compromised.
