Abstract

The invention discloses an optical imaging lens, which sequentially comprises a first lens, a second lens, a third lens, a fourth lens, a fifth lens and a sixth lens from an object side to an image side along an optical axis, wherein the second lens has focal power; the third lens has negative focal power; the fourth lens has focal power; the fifth lens has focal power, and an object side surfaceof the fifth lens is a concave surface; and the sixth lens has focal power. Half (Semi-FOV) of the maximum field angle of the optical imaging lens meets the condition that the Semi-FOV is larger than45 degrees and smaller than 60 degrees. The total effective focal length f of the optical imaging lens and the entrance pupil diameter EPD of the optical imaging lens meet the condition that f / EPD issmaller than 1.7. The total effective focal length f of the optical imaging lens and the curvature radius R8 of the image side face of the fourth lens meet the condition that R8 / f is larger than 0 andsmaller than 0.7.

Description

technical field [0001] The present application relates to the field of optical elements, in particular, to an optical imaging lens. Background technique [0002] With the rapid development of the field of portable electronic devices such as smart phones, the functions of portable electronic devices such as smart phones are increasing, and users have higher and higher requirements on the appearance and performance of smart phones and the like. At present, users have more and more demands for smart phones with large screens, and the fingerprint unlocking function under the screen has become one of the main reasons for users to demand smart phones with large screens. However, the under-screen imaging lenses used for under-screen fingerprint unlocking on the market have poor light transmission and cannot further meet the needs of users. Contents of the invention [0003] One aspect of the present application provides such an optical imaging lens, the optical imaging lens incl...
