Abstract

PURPOSE:To obtain a low magnification supermicrolens with various aberrations well corrected, by satisfying prescribed conditions in a lens system consisting of 8-group 13 lenses where negative, positive, positive, negative, negative, positive, positive, and positive groups are arranged in order from the magnifying side. CONSTITUTION:In a lens system consisting of 8-group 13 lenses where the front group of a negative meniscus lens with positive and negative lenses joined and rear groups of a positive single lens, a positive meniscus single lens, a negative meniscus lens with positive and negative lenses joined, a negative meniscus lens with negative and positive lenses joined, a positive single lens, a positive lens with positive and negative lenses joined, and a positive meniscus lens with positive and negative lenses joined are arranged in order from the magnifying side, conditions 1.2f<d3<2.5f, n5<n4, and n7>n8 are satisfied. (f) is the resultant focal length of the whole of the system, and di and ni are the interval between refracting surfaces and the refractive index of the i-th lens. Thus, a low magnification supermicrolens with various aberrations well corrected is obtained.
