Imaging lens

摘要

Disclosed herein is an imaging lens, including: a first lens having positive (+) power and being biconvex; a second lens having negative (−) power and being concave toward an image side; a third lens having positive (+) power and being biconvex; a fourth lens having positive (+) power and being convex toward the image side; and a fifth lens having negative (−) power and being concave toward the image side, wherein the first lens, the second lens, the third lens, the fourth lens, and the fifth lens are sequentially disposed from an object side.

1. An image lens unit, comprising:
a first lens having positive (+) power and being convex toward an object side; a second lens having negative (−) power and being concave toward an image side; a third lens being convex toward the image side; a fourth lens having positive (+) power and being convex toward the image side; and a fifth lens having negative (−) power and being concave in the center toward the image side, wherein a distance TTL on an optical axis from an object-side surface of the first lens to an image sensor and a total focal length F of an imaging lens satisfy the following conditional expression:
1.1 wherein the first lens, the second lens, the third lens, the fourth lens and the fifth lens are arranged in order from the object side to the image side.
