Abstract
A medical imaging device in accordance with the present application includes a color separation prism, a fluorescence image sensor, a visible light image sensor, and a bandpass filter. The color separation prism splits light into first light belonging to a visible light wavelength band and second light belonging to a fluorescence wavelength band. The fluorescence image sensor is provided at an output side of the color separation prism and is configured to image at least part of the second light belonging to the fluorescence wavelength band separated by the dichroic film. The visible light image sensor is provided at the output side of the color separation prism and is configured to image at least part of the first light belonging to the visible light wavelength band separated by the dichroic film. The bandpass filter is disposed between the color separation prism and the fluorescence image sensor.
