| 主权项 | 1. A microscope objective lens, wherein the microscope objective lens satisfies the following conditional expressions (1) and (2) 0.05<NA<0.4 (1) 3 mm<D/NA<50 mm (2) where, NA denotes a numerical aperture on an object side of the microscope objective lens, and D denotes a sum of thicknesses of all lenses included in the microscope objective lens, and wherein a parfocalizing distance PD of the microscope objective lens is calculated by the following expression (5) PD=45+15 m (5) where, m is −1, 0, 1, 2, 3, or 4. | ||
