Abstract
The present disclosure discloses a camera optical lens. The camera optical lens including, 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, and a sixth lens. The first lens is made of plastic material, the second lens is made of plastic material, the third lens is made of plastic material, the fourth lens is made of plastic material, the fifth lens is made of glass material, and the sixth lens is made of plastic material. The camera optical lens further satisfies specific conditions.
Claims20
A camera optical lens comprising of six lenses, from an object side to an image side in sequence:
- a first lens, a second lens, a third lens, a fourth lens, a fifth lens, and a sixth lens, and there are no preceding lenses on the object side of the first lens, no intervening lenses between adjacent lenses of the six lenses, and no subsequent lenses on the image side of the sixth lens;
- wherein the camera optical lens further satisfies the following conditions:
- −5≤f1/f≤−3;
- 1.7≤n5≤2.2;
- 0.03≤d9/TTL≤0.1;
- 0.71≤f12/f≤2.27;
- where
- f:
- a focal length of the camera optical lens;
- f1:
- a focal length of the first lens;
- f12:
- a combined focal length of the first lens and the second lens;
- n5:
- a refractive index of the fifth lens;
- d9:
- a thickness on-axis of the fifth lens;
- TTL:
- a total optical length of the camera optical lens from an object side surface of the first lens to an image surface.
