Abstract
An optical imaging lens and an imaging equipment comprising: a first, second, and seventh lens each with focal power and a convex surface on an object side and a concave surface on an image side; a third lens, fourth, and fifth lens each with positive focal power and having a convex surface on the object side and a convex surface on the image side; a sixth lens with negative focal power, having an object side surface being a concave surface and an image side surface being a concave surface; and a diaphragm. The optical imaging lens has the characteristics of super large aperture, long focal length, and high resolution, and can meet the requirements for small field of view and high resolution, e.g., in vehicle-mounted devices.
