Patent ID: 8570667

Claim:
An optical lens assembly for image capture, sequentially arranged from an object side to an image side with no intervening lenses, comprising: a first lens element with positive refractive power, having a concave object-side surface in proximity to an optical axis and a convex image-side surface in proximity to the optical axis; a second lens element with negative refractive power, having a concave object-side surface in proximity to the optical axis and a convex image-side surface in proximity to the optical axis; and a third lens element with positive refractive power, having a convex object-side surface in proximity to the optical axis and a convex image-side surface in proximity to the optical axis, wherein the optical lens assembly for image capture has a total of three lens elements with refractive power; wherein f is a focal length of the optical lens assembly for image capture, f 1 is a focal length of the first lens element, and the condition of 1.0<f/f 1 <1.9 is satisfied; and wherein R 5 is a curvature radius of the object-side surface of the third lens element, R 6 is a curvature radius of the ima e-side surface of the third lens element, and the condition of −0.7<R 5 /R 6 <0 is satisfied.
