Patent ID: 7085077

Claim:
An image lens array, from object side to image side, comprising a first lens, an aperture, a second lens and a third lens; and wherein the first lens is a positive meniscus lens with positive refractive power and has a convex surface facing the object side; the aperture is located behind the first lens; the second lens is positive meniscus lens with positive refractive power and has a convex surface facing the image side; the third lens is a positive meniscus lens with positive refractive power and has a convex surface facing the object side; and the first lens, the second lens and the third lens are made of the same plastic material, a focal length of the image lens array is f, a combined focal length of the first and second lenses is f12, a relation between the f and f12 can satisfy the equation: 1.0<f12/f<1.3; the focal length of the image lens array is f, a focal length of the second lens is f2, and then f and f2 can satisfy the equation: 2.0<f2<f<11.0; the focal length of the image lens array is f, a focal length of the third lens is f3, and then f and f3 can satisfy the equation: f3/f>5.0.
