Abstract: A microscope includes a condenser lens that is arranged removably and insertably with respect to a light path of light from a light source, and an objective that collects the light from the light source, which has been transmitted through a sample. A conditional expression below is satisfied when b is an exit pupil diameter of the objective and adet is a diameter of an area in a state in which the condenser lens has been removed from the light path, the area being included in an exit pupil plane of the objective and being an area through which the light from the light source, which has entered the objective through one point on the sample, passes: 1/20≦adet/b≦1/2 (1).

Abstract: An immersion microscope objective includes: a first lens group that consists of a first cemented lens consisting of a planoconvex lens and a first meniscus lens, the first meniscus lens having a thickness that is greater than the radius of curvature of the lens surface of the image side of the first meniscus lens; a second lens group that includes a plurality of cemented lenses; a third lens group that consists of a second cemented lens; and a fourth lens group that includes a third cemented lens consisting of a plurality of meniscus lenses. The objective satisfies the following: 2≤h1/h2≤4 (1) where h1 indicates an axial marginal ray height at a lens surface that is the closest to the object in the second cemented lens, and h2 indicates an axial marginal ray height at a lens surface that is the closest to the image in the second cemented lens.
