Abstract
The invention discloses a six-piece optical lens for capturing image and a six-piece optical module for capturing image. In order from an object-side surface to an image-side surface, the optical lens along the optical axis comprises a first lens with refractive power; a second lens with refractive power; a third lens with refractive power; a fourth lens with refractive power; a fifth lens with refractive power; a sixth lens with refractive power, and at least one of the image-side surface and object-side surface of each of the six lens elements is aspheric. The optical lens can increase aperture value and improve the imagining quality for use in compact cameras.
