Document Type and Number:
WIPO Patent Application WO/2019/052220
Kind Code:
A1
Abstract:
Disclosed in the present application is an optical imaging lens. The optical imaging lens comprises, from an object side to an image side along an optical axis, a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens, and a seventh lens in sequence. The first lens has positive optical power, the object side surface thereof is a convex surface, and the image side surface thereof is a concave surface; the second lens has negative optical power, the object side surface thereof is a convex surface, and the image side surface is a concave surface; the third lens has positive or negative optical power; the fourth lens has positive or negative optical power, and the object side surface thereof is a concave surface; the fifth lens has positive or negative optical power; the sixth lens has positive or negative optical power; the seventh lens has negative optical power, the object side surface is a concave surface, and the image side surface is a concave surface; the total effective focal length f of the optical imaging lens and the entrance pupil diameter (EPD) of the optical imaging lens satisfy f/EPD≤1.70.
