Abstract
The present invention provides a visible and infrared light image-taking optical system which can facilitate changing a wavelength of infrared light used to take an infrared video image with an infrared light camera and which can achieve an infrared video image not affected by infrared light of any wavelength other than a desired wavelength, by separating object light incident on an image-taking optical system into object light in a visible light region and object light in an infrared light region and taking an object image formed by each object light for each object light in each wavelength region decomposed by the color separation optical system.
