Abstract

The present invention discloses an optical imaging lens, which includes ten lenses, which are arranged in order from the object side to the image side: a first lens with positive focal power, a second lens with focal power, a third lens with focal power, a fourth lens with focal power, a fifth lens with negative focal power, a sixth lens with focal power, a seventh lens with focal power, an eighth lens with focal power, a ninth lens with positive focal power, and a tenth lens with negative focal power; wherein each lens is independent of each other and has an air gap on the optical axis. By using the technical solution of the present invention, a ten-piece camera lens group with a large image surface is provided, which can better meet people's needs for high pixels and high definition for daily mobile phone photography; and at least three lenses from the first to the tenth lenses are made of plastic material, which can reduce the quality of the imaging lens and better balance various aberrations.
