Abstract
An optical lens assembly includes, in order from an object side to an image side: a first lens with negative refractive power; a second lens with negative refractive power; a third lens with positive refractive power; a stop; a fourth lens with positive refractive power; a fifth lens with negative refractive power; and a sixth lens with positive refractive power. Half of a maximum field of view of the optical lens assembly is HFOV, an entrance pupil diameter of the optical lens assembly is EPD, a distance from an object-side surface of the first lens to an image plane along an optical axis is TL, a central thickness of the fifth lens along the optical axis is CTS, a radius of curvature of an image-side surface of the fifth lens is R10. Following conditions are satisfied: 3.81 deg.<HFOV*EPD/TL<6.24 deg. and −1.9 mm<CT5*R10<−0.2 mm.
