Abstract:
In an optical measuring device, the visual observation section includes: a white light source which emits white light; a first objective lens arranged between the white light source and measurement object, through which the white light emitted from the white light source and return light from the measurement object transmit; a plurality of tube lenses which change a magnification of the return light passing through the first objective lens to a predetermined magnification; and a lens switching mechanism which can selectively switch the tube lenses so as to select one of the tube lenses to be arranged on the return light, and the special observation section includes: a special light source which emits special light; and a second objective lens arranged between the special light source and measurement object, through which the special light emitted from the special light source and return light from the measurement object transmit.
