Optical imaging camera shot and electronic device using same

Abstract

The invention relates to an optical imaging camera shot and an electronic device using the same. The optical imaging camera shot comprises five lenses sequentially from an object side to an image side along an optical axis. The image side of the first lens has a convex surface part in the area near the circumference; the object side of the second lens has a concave surface part in the area near the circumference; the image side of the second lens has a concave surface part in the area near the optical axis and a convex surface part in the area near the circumference; the object side of the third lens has a concave surface part in the area near the circumference; the fourth lens has positive refractive index, and the object side of the fourth lens has a convex surface part in the area near the optical axis; and the object side of the fifth lens has a convex surface part in the area near the optical axis, and meets the expressions T5 / G23>=1.1 and G45>G34. The electronic device comprises a case and an image module, and the image module comprises the optical imaging camera shot, a lens cone, a module holder 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 trend of thinner and lighter cameras also increases the demand for miniaturization of image modules. In order to reduce the size of the optical lens, the length of the optical lens installed in the image module needs to be shortened accordingly. However, in order to avoid the degradation of the 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 lenses a...

[0003] U.S. Patent Publication No. 8760775 and U.S. Patent Publication No. 20140078600 both disclose an optical lens composed of five lenses. However, the system length of these optical lenses cannot be effectively reduced to a certain length to meet the thinning of mobile phones. design requirements
