Optical Image Capturing System |
摘要 |
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 an object-side surface which can be convex; a second lens with refractive power; a third lens with refractive power; a fourth lens with refractive power; and a fifth lens which can have negative refractive power, wherein an image-side surface thereof can be concave, and at least one surface of the fifth lens has an inflection point; both surfaces of each of the five lenses are aspheric. The optical lens can increase aperture value and improve the imagining quality for use in compact cameras. |

1. An optical image capturing system, in order along an optical axis from an object side to an image side, comprising:
a first lens having refractive power; a second lens having refractive power; a third lens having refractive power; a fourth lens having refractive power; a fifth lens having refractive power; and an image plane; wherein the optical image capturing system consists of the five lenses with refractive power; at least two of the five lenses each has at least an inflection point on at least a surface thereof; at least one of the lenses from the first lens to the fifth lens has positive refractive power; the fifth lens has an object-side surface, which faces the object side, and an image-side surface, which faces the image side, and both the object-side surface and the image-side surface of the fifth lens are aspheric surfaces; wherein the optical image capturing system satisfies:
1.2≦f/HEP≦6.0;and0.5≦HOS/f≦5.0; where f1, f2, f3, f4, and f5 are focal lengths of the first lens to the fifth lens, respectively; f is a focal length of the optical image capturing system; HEP is an entrance pupil diameter of the optical image capturing system; and HOS is a distance in parallel with the optical axis from an object-side surface of the first lens to the image plane. |
