Optical imaging lens and electronic device comprising the same |
| 摘要 |
An optical imaging lens includes a first, second, third and fourth lens element, and an aperture stop positioned between the second and third lens elements. The first lens element has an object-side surface with a convex portion in a vicinity of its periphery, the second lens element has an image-side surface with a concave portion in a vicinity of the optical axis, the third lens element has an image-side surface with a convex portion in a vicinity of the optical axis, the fourth lens element is made of plastic and has an object-side surface with a concave portion in a vicinity of the optical axis, and the optical imaging lens set does not include any lens element with refractive power other than said first, second, third and fourth lens elements. |

1. An optical imaging lens set, from an object side toward an image side in order along an optical axis comprising: a first lens element, a second lens element, an aperture stop, a third lens element and a fourth lens element, said first to fourth lens elements having an object-side surface facing toward the object side as well as an image-side surface facing toward the image side, wherein:
said first lens element has an object-side surface with a convex part in a vicinity of the its periphery; said second lens element has an image-side surface with a concave part in a vicinity of the optical axis, and said second lens element has negative refractive power; said aperture stop is disposed between said second lens element and said third lens element; said third lens element has positive refractive power, and has an image-side surface with a convex part in a vicinity of the optical axis; said fourth lens element is made of plastic material and has positive refractive power, and has an object-side surface with a concave part in a vicinity of the optical axis; and the optical imaging lens set does not include any lens element with refractive power other than said first, second, third and fourth lens elements. |
