PROBLEM TO BE SOLVED: To provide a zoom microscope with high expandability which can be used for contrast observation (e.g., differential interference observation, etc.) of a sample and in which other optical systems (e.g., a fluorescent incident light illumination system, etc.) can be arranged between an objective lens part and a zoom part if necessary. SOLUTION: A replaceable infinity compensation type objective lens 11, an aperture diaphragm 12, an afocal zoom system 13 and imaging optical system 14 are arranged in order from the side of the sample 10A, the aperture diaphragm 12 is arranged on the rear focal surface of the objective lens or in its vicinity and an optical member 20 for the contrast observation is attachably/detachable arranged between the objective lens and the afocal zoom system.
