Abstract:
1. An imaging lens comprising: a first lens having positive (+) power; a second lens having positive (+) power; a third lens having positive (+) or negative (−) power; a fourth lens having positive (+) or negative (−) power; a fifth lens having positive (+) or negative (−) power; and a sixth lens having negative (−) power, wherein the first lens, the second lens, the third lens, the fourth lens, the fifth lens, and the sixth lens are sequentially disposed from an object side, and wherein when it is assumed that the entire focal length of the imaging lens is F and a distance between a surface of the first lens toward the object side and a surface of the sixth surface toward an image surface side on an optical axis is DL, a conditional equation of 0.7<DL/F<1.2 is satisfied.
