Abstract

The present disclosure discloses an optical lens assembly which includes, 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. The first lens may have negative refractive power, a convex object-side surface, and a concave image-side surface. The second lens may have negative refractive power, a convex object-side surface, and a concave image-side surface. The third lens may have positive refractive power, and both object-side and image-side surfaces thereof are convex. The fourth lens may have positive refractive power, and both object-side and image-side surfaces thereof are convex. The fifth lens may have negative refractive power, and both object-side and image-side surfaces thereof are concave. The sixth lens may have positive refractive power, and both object-side and image-side surfaces thereof are convex.
