摘要： An optical imaging system includes a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens, and a seventh lens sequentially disposed in numerical order along an optical axis from an object side toward an imaging plane, wherein the seventh lens includes an optical portion configured to refract light, and a rib surrounding the optical portion; the rib includes a surface-treated area disposed in a first portion of an object-side surface of the rib and a first portion of an image-side surface of the rib, a first non-treated area disposed in a second portion of the object-side surface of the rib, and a second non-treated area disposed in a second portion of the image-side surface of the rib; and the first non-treated area and the second non-treated area overlap each other when viewed in a direction of the optical axis.
