Abstract

Provided is a camera optical lens, including first lens having negative refractive power, second lens having positive refractive power, third lens having positive refractive power, and fourth lens having negative refractive power, focal length of the camera optical lens is f, focal length of the first lens is f1, combined focal length of the third and fourth lenses is f34, on-axis thickness of the first lens is d1, on-axis distance between the first and second lenses is d2, total optical length of the camera optical lens is TTL, abbe number of the first lens is v1, following relational expressions are satisfied: −30.00≤f1/d1≤−8.00; 2.00≤TTL/f≤3.00; −2.30≤f34/f<−1.30; 58.00≤v1≤82.00; 0.25≤d2/TTL≤0.45. The camera optical lens has good optical performance, and is particularly suitable for mobile phone camera lens assembly, vehicle-mounted lens and WEB camera lens.
