PROBLEM TO BE SOLVED: To provide a microscopic device by which many actuation distances are selected without needing labor or cost for manufacturing of a new attachment lens or the like. SOLUTION: In the microscope device 1, by which the distance between an observation object 50 and the top part of a microscope 10 is adjusted by the attachment lens 30, it is provided with plural adapters 20 having different sizes in an optical axis direction, and the male screw 21a of the adapter 20 is screwed to the female screw 11a of the top part of the microscope 10, and also a female screw 22a is screwed to the attachment lens 30. Thus, the many actuation distances are selected by the small number of the attachment lenses 30, without having to spend handling time and expense of preparing the new attachment lens 30 and to change the attaching position of the microscope only by replacing the adapter 20, so that the flexibility of design is increased.
