PROBLEM TO BE SOLVED: To provide a microscope objective lens that is compact and that enables a wider range of observation.SOLUTION: A microscope objective lens is characterized in that the maximum inclination (CRA) of a principal ray (units: degrees) between a microscope objective lens and an imaging lens satisfies conditional expression (1): 5<CRA<22 (1), CRA=tan(IH/(Ftl×Q×P)), where Ft1 is the focal length of an infinity-corrected imaging lens, IH is the maximum image height, Q is an intermediate lens barrel magnification coefficient, and P is a projection magnification coefficient. |
