Abstract
An imaging system includes a light source emitting light at least a first excitation wavelength band to excite a first fluorescence material emitting a first fluorescence in a near-infrared wavelength band and light a second excitation wavelength band to excite a second fluorescence material emitting a second fluorescence in a visible wavelength band, a first image sensor receiving light including the first fluorescence and outputs a first imaging signal, a second image sensor receives light including the second fluorescence and output a second imaging signal, an optical element that separates the first fluorescence into a first optical branch and the second fluorescence into a second optical branch; and a pass filter in the first optical branch transmitting light having a near-infrared wavelength band and block light having a wavelength equal to or less than a predetermined wavelength belonging the visible wavelength band.
