Patent ID: 7443614

Claim:
An image pickup lens, in order from an object side to an image side along an optical axis thereof, comprising: a first lens element of positive refractive power, the first lens element having a meniscus shape and an object-side surface convex toward the object side; a second lens element of positive refractive power, the second lens element having a meniscus shape and an image-side surface convex toward the image side; and a third lens element of negative refractive power, the third lens element having an aspheric surface on the image side; wherein, the first, second and third lens elements satisfy the following conditions: 0.85 ≤ v ⁢ ⁢ 1 v ⁢ ⁢ 2 ≤ 1.15 0.85 ≤ v ⁢ ⁢ 2 v ⁢ ⁢ 3 ≤ 1.25 where, v 1 represents the Abbe number at the d-line of the first lens element, v 2 represents the Abbe number at the d-line of the second lens element, and v 3 represents the Abbe number at the d-line of the third lens element; the wavelength at the d-line being 587.5618 nm; and wherein the first and second lens elements have the same Abbe number at the d-line.
