摘要： An imaging lens, although compact, has satisfactorily corrected aberrations. The imaging lens is configured by disposing, in sequence from the object side, a stop (ST); a first lens (L1), which has a double convex shape near the optical axis; a meniscus-shaped negative second lens (L2) which has near the optical axis a convex surface facing the object side; a meniscus-shaped positive third lens (L3) which has near the optical axis a concave surface facing the object side; and a positive fourth lens (L4) which has a double convex shape near the optical axis. In the configuration, the refractive power of the first lens (L1) is greater than the refractive power of each of the second lens (L2), the third lens (L3), and the fourth lens (L4).
