    摘要: An optical microscope has a revolver for selectively inserting a plurality of objective lenses including a low-magnification (very-low-magnification) objective lens on an optical axis for observation light. In fluorescence observation using the low-magnification objective lens, the effective diameter of an observation optical system is set larger than that of an illumination optical system. With this arrangement, fluorescence observation using the low-magnification objective lens can be stably performed. A cube unit having a plurality of cubes corresponding to the respective microscopic methods is arranged in the optical microscope. An auxiliary lens serving as a very-low-magnification objective lens is mounted in this cube unit. The auxiliary lens can be automatically used in observation using the very-low-magnification objective lens. With this arrangement, a compact optical microscope excellent in operability can be realized.

    摘要: A microscope system has a stage on which an observation sample, including an observation object and a transparent member, is to be placed. An objective lens is placed to face the observation sample placed on the stage, and a focusing unit moves at least one of the stage and the objective lens to perform a focusing operation. An autofocus unit controls a focusing driving unit by a so-called Through-the-Lens: TTL system. After autofocus is performed for the transparent member by the autofocus unit, the focusing driving unit makes at least one of the stage and the objective lens move by a predetermined constant amount.
