IMAGE PICKUP LENS, IMAGE PICKUP MODULE, AND PORTABLE INFORMATION DEVICE

摘要

In order to provide an image pickup lens, an image pickup module, and a portable information device that make it possible to reduce the risk of deterioration in optical characteristic by achieving satisfactory resolving performance in an area surrounding a shot image, an image pickup lens includes a first lens having an Abbe number of greater than 45 and second lens having an Abbe number of greater than 45 and satisfies mathematical expression (1): −3.6<f2/f1<−2.5  (1) where f1 is the focal length of the first lens and f2 is the focal length of the second lens.
