Abstract

PURPOSE:To maintain the maintain the high performance of image formation even if the thickness of a cover glass changes, by forming a lens system consisting of the 1st group of a positive concave cemented meniscus lens, the 2nd group of a positive or cemented lens positive and the 3rd group having the positive synthetic refractive index respectively at the side of a subject and satisfying the specific conditions. CONSTITUTION:For a lens system including the 1st-3rd lenses L1-L3, the synthetic focal distance of the whole lens system is referred to as (f) along with the curvature radius (r) of each lens surface, the refractive index (n) and the Abb number (nu) respectively. The order counted from the side of a subject is shown by the figures attached to each of the above-mentioned factors. When the tertiary aberration coefficient (spherical aberration) of the 2nd lens L2 is referred to as Ik in the case of f=1, the seven conditional equations are satisfied. Thus the aberration is compensated with high accuracy over a wide range of fluctuation for the parallel flat glass which is provided between the body surface and the 1st lens L1 by shifting the lens L2 on the optical axis.
