A five-piece optical lens for capturing image and a five-piece optical module for capturing image, along the optical axis in order from an object side to an image side, include a first lens with positive refractive power having a convex object-side surface; a second lens with refractive power; a third lens with refractive power; a fourth lens with refractive power; and a fifth lens with negative refractive power; and at least one of the image-side surface and object-side surface of each of the five lens elements are aspheric. The optical lens can increase aperture value and improve the imagining quality for use in compact cameras.

Optical image capturing system

The present disclosure illustrates an optical image capture module comprising an optical lens assembly, an aperture stop and an image plane. The optical lens assembly in order from an object side toward an image side comprising: a first lens element, having positive refractive power and a convex object-side surface adjacent to the optical axis; a second lens element, a third lens element and a fourth lens element which have refractive power adjacent to the optical axis; a fifth lens element having refractive power and a concave image-side surface adjacent to the optical axis; a sixth lens element having negative refractive power and a convex surface image-side surface adjacent to the optical axis, at least one of the object-side surface and image-side surface of the sixth lens element being aspheric and having at least one inflection point located between the optical axis and the peripheral surface.

Optical image capture module

The present disclosure illustrates a five-piece imaging lens assembly which includes an aperture stop, an optical lens assembly, an image plane. The optical lens assembly, in order from an object side to an image side, includes a first lens element with positive refractive power adjacent to the optical axis and having a convex object-side surface, a second lens element with negative refractive power adjacent to the optical axis and having a concave object-side surface, a third lens element and a fourth lens element with refractive power adjacent to the optical axis, and a fifth lens element with negative refractive power adjacent to the optical axis and having a convex image-side surface. At least one of the object-side surface and the image-side surface of the fifth lens element has an inflection point. The image plane is for image formation for an object.

Five-piece imaging lens assembly

A lens assembly includes a lens set which includes a first lens, a second lens, a third lens and a fourth lens arranged in sequence along an optical axis. The first lens has a positive optical power. The second lens has a positive optical power. The third lens has a negative optical power. The fourth lens has a positive optical power, and has an image-side surface, an object-side surface, and a peripheral surface interconnecting the two. At least one of the object-side and image-side surfaces has an inflection point located between the optical axis and the peripheral surface. The lens assembly satisfies 15&#x3c;HFOV/f&#x3c;50, in which, HFOV represents one half of a maximum angle of view of the lens assembly, and f represents a focal length thereof.
