OPTICAL SYSTEM |
| 摘要 |
There is provided an optical system including: a first lens having refractive power, an object-side surface thereof being convex toward an object; a second lens having positive refractive power; a third lens having negative refractive power; a fourth lens having positive refractive power; and a fifth lens having negative refractive power, wherein the optical system satisfies Conditional Expression 1:;T34/T23>8.0 [Conditional Expression 1]where T23 is a distance (air gap) [mm] between the second and third lenses, and T34 is a distance (air gap) [mm] between the third and fourth lenses. |

1. An optical system comprising in order from an object side to an image side:
a first lens having refractive power, an object-side surface thereof being convex toward an object; a second lens having positive refractive power; a third lens having negative refractive power; a fourth lens having positive refractive power; and a fifth lens having negative refractive power, wherein the optical system satisfies Conditional Expression 1:
T34/T23>8.0 [Conditional Expression 1] where T23 is a distance (air gap) [mm] between the second and third lenses, and T34 is a distance (air gap) [mm] between the third and fourth lenses. |
