Patent ID: 8488239

Claim:
A medical stand device comprising: an arm configured to support a microscope; a stand main body configured to support the arm; a light generating unit installed inside the stand main body, the light generating unit including a xenon lamp as a light source, and being configured to generate illumination light using the xenon lamp, which is supplied to the microscope; and optical means configured to cut out the illumination light having a wavelength of a peak or longer in an emission spectrum of the xenon lamp, the peak substantially firstly appearing as infrared light on a visible light side of an infrared region in the emission spectrum and configured to transmit or reflect the illumination light including a wavelength of excitation light of an indocyanine green or shorter, by cutting out the illumination light having wavelengths longer than a threshold wavelength, the threshold wavelength being longer than 805 nm and shorter than 815 nm, wherein the optical means is fixed on an optical path of the illumination light from the light generating unit to the microscope.
