COLOR SEPARATION PRISM AND IMAGING DEVICE

摘要

This color separation prism includes a filter that transmits a portion of the visible light from an object and transmits invisible light from the object with a prescribed wavelength bandwidth, and a first prism, second prism, and third prism. The light passing through the filter is incident onto the first prism, and the first prism emits light reflected from a first reflective film. The first reflective film reflects a first color component of the visible light and a portion of the invisible light among the light incident onto the first prism and transmits a second color component and a third color component of the visible light and the rest of the invisible light. The second prism emits the light reflected from a second reflective film; the second reflective film reflects the second color component of the visible light and a portion of the invisible light among the light incident onto the second prism and transmits a third color component and the rest of the invisible light. The third prism emits the light transmitting through the second reflective film. The first and second reflective films are configured to distribute the light quantities of the visible light and the invisible light emitted from each prism to become substantially even.
