1. An optical imaging lens, sequentially comprising, from an object side to an image side:
a first lens with focal power, having an object side surface being a convex surface and an image side surface being a concave surface;
a second lens with negative focal power, having an object side surface being a concave surface and an image side surface being a concave surface;
a third lens with positive focal power, having an object side surface being a convex surface and an image side surface being a convex surface;
a fourth lens with positive focal power, having an object side surface being a convex surface and an image side surface being a convex surface;
a fifth lens with positive focal power, having an object side surface being a convex surface and an image side surface being a convex surface;
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 the fifth lens and the sixth lens formed into a cemented body;
a seventh lens with negative focal power, having an object side surface being a convex surface and an image side surface being a concave surface; and
a diaphragm, disposed between the first lens and the third lens.
