Abstract
A microscope body is adapted to compensate for the deliberately introduced 0.6 percent lateral color of an infinity corrected microscope objective. This compensation of the lateral color by the microscope body is done without introducing objectionable axial color aberration. The microscope body is typically a trinocular body which provides an image to binocular eyepieces for observation by a user or alternatively to both the eyepieces and to a focal plane of a camera.
