Abstract

PURPOSE: To obtain the high contrast imaging performance free from any flare by forming the 2nd lens face to the specified aspherical face in the rear stop Tesser type lens constituted by a meniscus positive lens, a biconcave lens and the lens comprising cementing a negative lens and a biconvex lens, subsequently from the subject side.
CONSTITUTION: An aspherical face is incorporated to the 2nd lens face of the Tessar type lens which is constituted by a meniscus positive lens of which the convex is faced to the subject, a biconcave lens and the lens comprising cementing a negative lens and a biconvex lens and which is disposed with a stop behind the final lens face. An X-axis and a Y-axis intersecting orthogonally with the X-axis are taken in the advance direction of light on the optical axis and (1), (2) formulas are satisfied where the deviations in the X-axis direction of the spherical face having the radius of vertex curvature to determine the focal length (f) and aspherical face are assumed to be ΔX, the deviation of the aspherical face in its effective maximum position to be ΔXa and the deviations in the position half said position to be ΔXb. Thereby, the high contrast imaging performance free from any flare at all over the entire image plane may be obtained.
