ABSTRACT:
An objective lens system for a microscope has a high magnification and high numerical aperture. Corrections for various aberrations, and especially coma, can be made over a wide field of view. The system can be used as an objective lens system for a fluorescence microscope. The objective lens system contains a first lens group which has multiple lenses placed in sequence as counted from the object side. The first lens group has a positive focal power. A second lens group includes a first compound lens, prepared by cementing a negative meniscus lens with its convex surface facing the object side and a biconvex lens, and a second compound lens, prepared by cementing a biconcave lens and a biconvex lens. A third lens group has multiple lenses and a negative focal power. A change in aberration can be corrected for by moving the second lens group with respect to the first and third lens groups along the optical axis. The objective lens system meets certain prescribed conditions.
