Optical imaging lens and electronic device using the optical imaging lens

Abstract

The invention relates to an optical lens and an electronic device using the optical imaging lens. The optical imaging lens includes six lenses, the first lens has a positive refractive power, the object side of the first lens has a convex surface located in the vicinity of the circumference, and its image side has a convex surface located in the vicinity of the optical axis; the second The image side of the lens has a concave portion located in the vicinity of the optical axis; the object side of the third lens has a convex portion located in the vicinity of the circumference; the object side of the fourth lens has a concave portion located in the vicinity of the optical axis The object side of the fifth lens has a concave portion located near the optical axis; and the image side of the sixth lens has a concave portion located near the optical axis, and the material of the sixth lens is plastic. The electronic device of the present invention includes a casing and an image module. The image module includes an optical imaging lens, a lens barrel, a module rear seat unit, and an image sensor.

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 CMOS) technological progress and size reduction, the length of the optical lens loaded in the image module also needs to be shortened accordingly, but in order to avoid the decline of photographic effect and quality, good optical performance must still be taken into account when shortening the length of the optical lens. However, the most important characteristics of optical len...
