Abstract
An optical imaging lens includes first, second, third, fourth, fifth, and sixth lens elements, each having an object-side surface facing toward an object side and an image-side surface facing toward an image side. The image-side surface of the first lens element includes a concave portion in a vicinity of a periphery of the first lens element. The optical imaging lens as a whole has only the six lens elements having refractive power. The ratio between the f-number of the optical imaging lens and thicknesses of the lens elements satisfies certain relations.
