Abstract: A digital camera imaging lens includes first, second and third lenses arranged in sequence from an object side toward an imaging surface side. The first lens is a meniscus lens having a positive power, whose convex surface faces the object side. The second lens is a meniscus lens having a negative power, whose concave surface faces the object side. The third lens is an aspherical lens having an inflection point on its object-side surface. An aperture stop is disposed between the first and second lenses. The imaging surface is defined by an element surface of a photosensor.

Abstract: An imaging lens (100) comprising, arranged sequentially from the object side, a positive-meniscus first lens (1) with its convex plane facing the object side, a negative-power-meniscus second lens (2), and a positive-power third lens (3), the second and third lenses (2, 3) functioning as correction lenses. The first lens (1) has a strong power, and both the second and third lenses (2, 3) are aspherical on opposite planes. When the synthetic focal distance of the imaging lens is f, the focal distance of the first lens f1, the distance from the incident surface on the object side to the imaging surface of the first lens (1) ?d, and the Abbe number of the second lens ?d2, the following conditional expressions are satisfied. 0.50<f1/f<1.5 (1) 0.50<?d/f<1.5 (2) 50>?d2 (3). Accordingly, a small, low-cost imaging lens capable of high-quality imaging can be realized.
