Linsenabbildungssystem

An imaging lens system includes, in the named order from the side of an object toward an image surface, a light amount diaphragm, a first lens having a positive power with a main power on the side closer to the image surface, a meniscus-shaped second lens having a negative power with a strong concave surface turned toward the image surface. Thus, it is possible to provide the imaging lens system in which a sufficiently high resolution can be obtained, while meeting the demand for a reduction in entire length of an optical system to provide the compactness.
