Abstract

See full text

An imaging lens is composed of a first lens having a negative meniscus shape with a convex surface on the object side, a negative second lens, a positive third lens, an aperture stop, a negative fourth lens, and a positive fifth lens disposed in order from the object side. The fourth and the fifth lens are cemented with an interface which is convex on the object side and has an aspherical shape. If the radius of curvature is taken as R9 and the focal length of the entire system is taken as f, the imaging lens satisfies a conditional expression given below:

description='In-line Formulae' end='lead'1.0<R9/f  (1).description='In-line Formulae' end='tail'
