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