Abstract
Abstract Objective lens systems for use in microscopes, constructed as five components and eight lenses of the Gauss type, consisting of a first component of a single positive lens, a second component of a compound positive lens, third and fourth components of compound negative lenses, and a fifth component of a single positive lens, all lenses arranged in succession from the side of the object, defined by specific conditions that are disclosed herein.
