Abstract
PURPOSE:To correct various aberrations excellently by composing a lens system of the 1st positive lens group, 2nd negative lens group and 3rd positive lens group, and by making them meet prescribed requirements. CONSTITUTION:A lens system consists of the 1st positive lens group, and 2nd lens group of a negative cemented meniscus lens having a convex surface on an object side, and the 3rd positive lens group. Then, expressions (1)-(4) hold. (In the expressions, refractive indexes of the lens in the 1st group and both the lenses in the 2nd group are n1, and n2 and n3, an air gap between the 1st group and the 2nd group is d2, and the thicknesses of both the lens in the 2nd group are d3 and d4; and radii of curvature of the object-side surface and cemented surface of the 2nd group lens are r3 and r4, and the focal length of the whole system is f.) Consequently, although one lens group is eliminated as compared with a conventional system, an objective lens whose various aberrations are corrected similarly to or more excellently than the conventional one is obtained.
