Imaging lens

An imaging lens comprising:

• in order from an object side of the imaging lens,
• a first lens having a positive refracting power;
• a second lens having a concave surface on the object side and having a negative refracting power;
• and
• a third lens having a positive refractive power and a meniscus shape having a convex surface on the object side and at a vicinity of an optical axis thereof,
• wherein at least one surface of the first lens, the second lens and the third lens is aspherical, and the imaging lens satisfies conditional equations:
• 0.7<f1/f<1.3 (1)
• 0.25<D2/f<0.50 (2)
• 55<ν123 (3)
• |ν123−ν2|<5 (4)
• 0.3<|f2/f|<1.0 (5)
• wherein
• f is a focal length of the imaging lens;
• f1 is a focal length of the first lens;
• f2 is a focal length of the second lens;
• D2 is an interval between the first lens and the second lens on the optical axis
• ν123 is an average of Abbe numbers of the first lens, the second lens and the third lens;
• and
• ν2 is an Abbe number of the second lens.
