Abstract
An optical imaging lens may include a first, a second, a third, a fourth, a fifth, a sixth, a seventh, and an eighth lens elements positioned in an order from an object side to an image side. Through designing concave and/or convex surfaces of the eight lens elements, the improved optical imaging lens may provide better imaging quality while the system length of the lens may be shortened, the F-number may be reduced, the field of view may be extended, and the image height may be increased.
