Abstract
An optical imaging lens includes an aperture stop and first, second, and third lens elements from an object side to an image side in order along an optical axis. Each of the lens elements has an object-side surface and an image-side surface. The image-side surface of the first lens element has a convex portion in a vicinity of a periphery. The second lens element has negative refracting power, and the image-side surface of the second lens element has a convex portion in a vicinity of the optical axis. The optical imaging lens satisfies: 2×ν1≦ν2+ν3, wherein ν1, ν2, and ν3 are respectively the coefficients of dispersion of the first, second, and third lens elements. A mobile device is also provided.
