Abstract
An optical imaging system is provided. The optical imaging system includes a first lens, a second lens, a third lens, and a fourth lens arranged in order from an object side toward an image plane, wherein the first lens may be formed of glass, and wherein a conditional expression 70<v1 and 0.8≤OAL/f≤0.9 may be satisfied, where v1 is an Abbe number of the first lens, OAL is a distance from an object-side surface of the first lens to the image plane, and f is a total focal length of the optical imaging system.
