る色分解系を有した撮影装置。 The light flux that has passed through the photographic lens is divided into a plurality of light fluxes having predetermined spectral characteristics through a color separation system including at least one prism having a part of which has a dichroic surface, and each of the plurality of light fluxes is imaged in a predetermined manner. In a photographing device having a color separation system configured to guide light onto a surface, a dichroic film for removing infrared light is applied to a surface of the prism having a dichroic surface closest to the photographing lens. A photographic device equipped with a color separation system.
