摘要： The present invention provides an optical imaging lens. The optical imaging lens comprises seven lens elements positioned in an order from an object side to an image side. Through controlling the convex or concave shape of the surfaces of the lens elements, the optical imaging lens may shorten system length and enlarge field of view and aperture size.

摘要： An optical imaging lens includes a first lens element, a second lens, an aperture stop, a third lens element and a fourth lens element from an object side to an image side in order along an optical axis, and each lens element has an object-side surface and an image-side surface. An optical axis of the image-side surface of the first lens element is convex and an optical axis of the image-side surface of the fourth lens element is concave. HFOV stands for the half field of view of the entire optical imaging lens and TTL is a distance from the object-side surface of the first lens element to an image plane along the optical axis to satisfy HFOV/TTL≤1.500°/mm.
