Abstract
A camera optical lens includes, from an object side to an image side: a first lens having positive refractive power; a second lens having positive refractive power; a third lens having negative refractive power; a fourth lens having positive refractive power; and a fifth lens having positive refractive power. The first lens is made of glass material. At least one of the second, third, fourth and fifth lenses is made of glass material. Working temperature of the camera optical lens ranges from −40° C. to 105° C. The camera optical lens satisfies following conditions: 1.50≤TTL/f≤4.00; 1.70≤n1≤2.20; and R3/R4≤−2.00, f denotes a focal length of the camera optical lens; TTL denotes a total optical length; n1 denotes a refractive index of the first lens; R3 denotes a central curvature radius of an object-side surface of the second lens, and R4 denotes a central curvature radius of an image-side surface of the second lens.
