Kind Code:
A1
Abstract:
A camera optical lens (10, 20, 30), which relates to the field of optical lenses, comprises nine lenses in total, namely, from an object side to an image side, a first lens (L1) having a positive refractive power, a second lens (L2), a third lens (L3), a fourth lens (L4), a fifth lens (L5), a sixth lens (L6), a seventh lens (L7), an eighth lens (L8) and a ninth lens (L9) in sequence, wherein the second lens (L2) has a negative refractive power, the optical camera lenses (10, 20, 30) have a focal length f, the first lens (L1) has a focal length f1, the second lens (L2) has an on-axis thickness d3, the on-axis distance from an image side face of the second lens (L2) to an object side face of the third lens (L3) is d4, and the following relational expressions are met: 2.00 ≤ f1/f ≤ 5.00 and 2.00 ≤ d3/d4 ≤ 10.00. The optical camera lens (10, 20, 30) meets the design requirements of a large aperture, a wide angle, and an ultra-thin thickness, while also having a good optical performance.
