Optical imaging lens and electronic device with optical imaging lens

Abstract

The invention relates to an optical imaging lens and an electronic device with the optical imaging lens. The optical imaging lens sequentially comprises five lens bodies from the object side to the image side. The image side face of the first lens body is provided with a convex face part located in the area near the circumference; the object side face of the second lens body is provided with a convex face part located in the area near the circumference, and the image side face of the second lens body is provided with a concave face part located in the area near the optical axis; the image side face of the third lens body is provided with a concave face part located in the area near the circumference; the object side face of the fourth lens body is provided with a concave face part located in the area near the optical axis; the image side face of the fifth lens body is provided with a concave face part located in the area near the optical axis, and the condition that ALT / G34<=7.7 is met. The camera device comprises an enclosure and an image module and further comprises the optical imaging lens, a lens cone, a module back seat unit and an image sensor. Thus, the lens length can be reduced, and good imaging quality can be kept.

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 popularization 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 components such as optical imaging lens, module holder unit and sensor. The thin and light trend of digital cameras also makes the miniaturization of image modules more and more demanding. For the technological progress and size reduction of CMOS), the length of the optical imaging lens loaded in the image module also needs to be shortened accordingly. performance.
