OPTICAL SYSTEM |
| 摘要 |
There is provided an optical system including a first lens, a second lens, a third lens, a fourth lens including a negative refractive power, a fifth lens including negative power, and a sixth lens. An image-side surface of the fourth lens is convex in a paraxial region. An image-side surface of the fifth lens is convex in the paraxial region. The sixth lens includes an image-side surface that is concave in the paraxial region. The first to sixth lenses are sequentially disposed from an object side to an image side. |
