Abstract
The present disclosure discloses an optical lens assembly including, sequentially from an object side to an image side along an optical axis, a first lens, a second lens, a third lens, a fourth lens, a fifth lens and a sixth lens. An object-side surface of the first lens is convex, and an image-side surface thereof is concave. The second lens has negative refractive power. The third lens has positive refractive power. The fourth lens has positive refractive power, and both an object-side surface and an image-side surface thereof are convex. The fifth lens has positive refractive power. The sixth lens has negative refractive power.
