Imaging lens

Abstract

The invention relates to an imaging lens which comprises a first lens element, a second lens element, a third lens element, a fourth lens element and a fifth lens element. The first lens element withpositive refractive power includes a convex surface facing the object side and a concave surface facing the image side. The second lens element has positive refractive power. The third lens element has negative refractive power. The fourth lens element with negative refractive power has a concave surface facing the object side. The fifth lens element with positive refractive power includes a convex surface facing the image side. The first lens element, the second lens element, the third lens element, the fourth lens element and the fifth lens element are sequentially arranged from the object side to the image side along the optical axis. The imaging lens satisfies the following conditions: (R51-R52) / (R51+R52) is larger than 1 and is less than 10, wherein the R51 is the curvature radius ofthe object side surface of the fifth lens, and the R52 is the curvature radius of the image side surface of the fifth lens.

Description

technical field [0001] The invention relates to an imaging lens. Background technique [0002] The development trend of today's imaging lens, in addition to the continuous development towards miniaturization, with different application requirements, it also needs to have the ability of light weight and high resolution. The known imaging lens can no longer meet the current needs, and another An imaging lens with a new architecture can meet the demands of miniaturization, light weight and high resolution at the same time. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an imaging lens with short overall length, light weight and high resolution, but still has good optical performance, aiming at the above-mentioned defects of the prior art. [0004] The technical solution adopted by the present invention to solve the technical problem is to provide an imaging lens including a first lens, a second lens, a third lens,...
