Camera optical lens comprising seven lenses of ++−−−+- and ++−+−+-refractive powers
The present disclosure relates to the field of optical lenses and provides a camera optical lens. The camera optical lens includes, from an object side to an image side: a first lens made of a plastic material; a second lens made of a plastic material; a third lens made of a plastic material; a fourth lens made of a plastic material; a fifth lens made of a glass material; a sixth lens made of a plastic material; and a seventh lens made of a plastic material. The camera optical lens satisfies following conditions: 1.51f1/f2.50; 1.70n52.20; −2.00f3/f42.00; −10.00(R13+R14)/(R13−R14)10.00; and 0.01d9/TTL0.20. The camera optical lens can achieve a high imaging performance while obtaining a low TTL.
