Patent attributes
A camera optical lens includes, from an object side to an image side, a first lens having a positive refractive power; a second lens having a negative refractive power; a third lens having a positive refractive power; a fourth lens; a fifth lens having a negative refractive power; a sixth lens; a seventh lens having a positive refractive power; and an eighth lens having a negative refractive power. The camera optical lens satisfies: 1.50≤f7/f≤4.00, 1.20≤R6/R5≤5.00 and 1.00≤d10/d12≤3.50, where f denotes a focal length of the camera optical lens, f7 denotes a focal length of the seventh lens, R5 denotes a curvature radius of an object-side surface of the third lens, and R6 denotes a curvature radius of an image-side surface of the third lens. The camera optical lens can achieve good optical performance while satisfying design requirements for ultra-thin, wide-angle lenses having large apertures.
