Claim Text:
1. A microscope system comprising: a microscope main unit that generates illumination light to be radiated onto a specimen and that detects detection light from the specimen; and a plurality of attachable/detachable objective lens units that are selectively attached to the microscope main unit, wherein the microscope main unit includes a raining mechanism that can move an attached one of the plurality of objective lens units in an optical axis direction, wherein each of the plurality of objective lens units includes a mounting device that is attachable to the microscope main unit and plurality of objective lenses each of which is mounted on the mounting device in an attachable/detachable manner, and each of which collects the detection light from the specimen; wherein the plurality of objective lens units comprise: wherein the first objective lens unit and the second objective lens unit are selectively attachable to the microscope main unit; wherein the second objective lens unit is attachable to the microscope main unit via a mounting adaptor that is fixed to a main body of the second mounting device when the second objective lens unit is attached to the microscope main unit; wherein a distance from a mounting position of the first objective lens unit at a side of the microscope main unit to a focal position of one of the first objective lenses that is attached to the first objective lens unit and that is placed in the optical path of the illumination light and a distance from a mounting position of the second objective lens unit to a focal position of one of the second objective lenses that is attached to the second objective lens unit and that is placed in the optical path of the illumination light are set to be mutually equal; wherein a dimension of the first mounting device in the optical axis direction from a microscope main unit side mounting position thereof to a first objective lens side mounting position is different from a dimension of the second mounting device in the optical axis direction from an adaptor side fixing position thereof to a second objective lens side mounting position, wherein the microscope main unit comprises a illuminator having an illumination optical system on an inside thereof, and a frame unit comprising the raising mechanism, wherein the frame unit includes a base portion provided in a horizontal direction and a body potion formed perpendicular to the base portion, and wherein the microscope system further comprises a height-increasing member which has a predetermined thickness and which is provided in an attachable/detachable manner between the illuminator and a top end of the body portion of the frame unit such that the height-increasing member adjusts a height of the illuminator.
