Abstract
The present disclosure relates to optical lens, in particular to a camera optical lens. The camera optical lens includes, in an order from an object side to an image side, a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens and a seventh lens. The first lens is made of plastic material, the second lens is made of glass material, the third lens is made of plastic material, the fourth lens is made of glass material, the fifth lens is made of plastic material, the sixth lens is made of plastic material, and the seventh lens is made of plastic material. The camera optical lens satisfies the following conditions: 1≤f1/f≤1.5; 1.7≤n2≤2.2; −2≤f3/f4≤2; 0.5≤(R13+R14)/(R13−R14)≤10; and 1.7≤n4≤2.2. The camera optical lens can obtain high imaging performance and a low TTL (Total Track Length).
