ことを特徴とするレンズ変換装置。 A lens exchange device that attaches and detaches the lens to a lens driving device that moves the lens in the optical axis direction to focus the object to be irradiated, the slider that moves toward and away from the optical axis direction; a lens support provided at the tip to support the lens; and a guide to support the slider so as to be movable toward and away from the slider in the optical axis direction and to guide the slider in the optical axis direction while regulating positional fluctuations around the optical axis direction. , comprising a guide support that is detachably attached to the lens drive device to support the guide, and a drive means that moves the slider toward and away from the slider in the optical axis direction, and the light of the lens supported by the lens support is provided. A lens converting device characterized in that the axis and the optical axis of a lens moved by a lens driving device are made to coincide.
