WIDE-ANGLE LENS ASSEMBLY |
| 摘要 |
A wide-angle lens assembly includes a first lens, a second lens, a third lens, a first stop, a fourth lens, a fifth lens and a sixth lens, all of which are arranged in sequence from an object side to an image side along an optical axis. The first lens is with negative refractive power. The second lens is with negative refractive power. The third lens is with positive refractive power. The fourth lens is with positive refractive power. The fifth lens is with negative refractive power. The sixth lens is with positive refractive power. The fifth lens satisfies 16.1≦Vd5≦23.9, wherein Vd5 is an Abbe number of the fifth lens. |
