Abstract
An optical imaging lens includes first, second, third, fourth, and fifth lens elements arranged in sequence from an object side to an image side along an optical axis. Each lens element has an object-side surface and an image-side surface. The image-side surface of the first lens element has a convex portion in an optical axis region. The second lens element has negative refractive power. The object-side surface of the second lens element has a convex portion in an optical axis region. The third lens element has positive refractive power. The image-side surface of the third lens element has a concave portion in an optical axis region. The object-side surface of the fourth lens element has a concave portion in an optical axis region. The object-side surface of the fifth lens element has a convex portion in an optical axis region.
