Patent ID: 11966016

Abstract:
A camera optical lens is provided, including 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 camera optical lens satisfies following conditions: −2.80≤f1/f≤−1.20; 1.20≤d9/d11≤1.90; 1.20≤(R7+R8)/(R7−R8)≤5.00; 0.70≤f2/f≤1.00, where f denotes focal length of the camera optical lens; f1 denotes focal length of the first lens; f2 denotes focal length of the second lens; R7 denotes curvature radius of object side surface of the fourth lens; R8 denotes curvature radius of image side surface of the fourth lens; d9 denotes on-axis thickness of the fifth lens; d11 denotes on-axis thickness of the sixth lens. The above camera optical lens can meet design requirements for large aperture, wide angle and ultra-thinness, while maintaining good imaging quality.
