ABSTRACT:
An imaging lens for an image pickup device consists of two lens components that may each consist of a lens element. In order from the object side, these lens components have negative and positive refractive power, with each lens component having two aspheric surfaces. A stop is positioned between the lens components so as to be closer to the image-side lens component. Specified conditions are satisfied in order to miniaturize the imaging lens, reduce manufacturing and assembly costs, and improve imaging performance.
