IMAGE PICKUP LENS, AN IMAGE PICKUP MODULE, AND A PORTABLE INTELLIGENCE USING A SOLID-STATE IMAGE SENSING DEVICE LOADED ON PORTABLE TERMINALS

摘要

PURPOSE: An image pickup lens, an image pickup module, and a portable intelligence are provided to simplify a manufacturing process by omitting a body tube and/or a lens holder. ;CONSTITUTION: An image pickup lens comprises a aperture stop(2), a first lens(L1), and a second lens(L2) sequentially to the direction of the upper surface from an object. A first lens with the refractive power of a plus is the meniscus lens for a convex surface from the object. A second lens with the refractive power of a minus is a lens for a concave surface from the object. The second lens has the concave shape in the center area among the sides for the upper surface. The abbe number of the first lens exceeds 45 and the abbe number of the second lens exceeds 45. The equation of -3.6f2/f1-2.5 is satisfied(F1 is the focal distance of the first lens and f2 is the focal distance of the second lens).;COPYRIGHT KIPO 2011
