OPTICAL SYSTEM |
| 摘要 |
An optical system includes a first lens having negative refractive power, of which an object-side surface is convex, a second lens having positive refractive power, a third lens having negative refractive power, of which an object-side surface is concave, a fourth lens having positive refractive power, of which an image-side surface is convex, and a fifth lens having negative refractive power and having a meniscus shape in which an object-side surface thereof is convex. The first to fifth lenses are sequentially disposed from an object side. An aberration improvement effect may be increased and high resolution and a wide angle may be implemented. |

1. An optical system comprising:
a first lens having negative refractive power, of which an object-side surface is convex; a second lens having positive refractive power; a third lens having negative refractive power, of which an object-side surface is concave; a fourth lens having positive refractive power, of which an image-side surface is convex; and a fifth lens having negative refractive power and having a meniscus shape in which an object-side surface of the fifth lens is convex, wherein the first to fifth lenses are sequentially disposed from an object side. |
