Abstract: The present invention includes, in order from an object: a first lens group G1 having positive refractive power; a second lens group G2 having negative refractive power; an aperture stop S; a third lens group G3 having positive refractive power; and a fourth lens group G4 having negative refractive power. The second lens group G2 has, in order from an object, a front group G2F having negative refractive power and a rear group G2R having an achromatic cemented lens including a positive lens and a negative lens. The second lens group G2 and the third lens group G3 move in opposite directions along an optical axis at least in a part of a variable power block. In this configuration, the following conditional expressions are satisfied, 0.4

Abstract: A microscope including an illumination optical system having an objective lens and a fly-eye lens, where: the fly-eye lens having a plurality of lens elements; in the illumination optical system, images of the plurality of lens elements are projected on a pupil of the objective lens; and the number (n 1 ) of the images of the lens elements projected inside the pupil of the objective lens is more than the number (n 2 ) of the images of the lens elements projected on an outer perimeter of the pupil of the objective lens. In the above observation optical system, a first objective lens having a first pupil diameter and a second objective lens having a pupil diameter larger than the first pupil diameter are switchable, and a number n 1 may be greater than a number n 2 with respect to the first objective lens.

Abstract: A confocal scanning microscope including: an objective system (second objective lens 23 and objective lens 24) illuminating a sample SA with illumination light; a scanning mechanism 31 scanning the sample SA to obtain an intensity signal; and a scanning optical system 32 provided between the scanning mechanism and the objective system. The scanning optical system composed of, in order from the scanning mechanism side, a first positive lens group G1, a second negative lens group G2, and a third positive lens group G3. The third lens group has two chromatic aberration correction portions each formed by a positive lens and a negative lens or negative lens and positive lens. Glass materials are selected such that one performs chromatization and the other performs achromatization, thereby providing a confocal scanning microscope capable of correcting lateral chromatic aberration generated in the objective system in the specific wavelength region by the scanning optical system.

Abstract: A zoom microscope includes: an observation optical system (3) having an exchangeable objective lens (31), an aperture diaphragm (32), an afocal zoom system (33), and an image forming optical system (34); and a zoom epi-illumination optical system (1). The zoom epi-illumination optical system (1) has an optical path which is also the optical path of the observation optical system (3) between the objective lens (31) and the afocal zoom system (33) so as to illuminate an object by incident light. In the zoom epi-illumination optical system (1), an image of a light source (11) is formed in the vicinity of the pupil position of the objective lens (31). This realizes a zoom microscope capable of performing fluorescent epi-illumination without shading in all the magnification ranges.
