ABSTRACT:
To form three different color optical images in close vicinity to each other on the same image forming plane in a tri-color separating optical system, the optical system comprising a lens for focusing a subject optical image on a green optical image forming plane (I.sub.g); dichroic mirrors or a dichroic prism for directly passing a green color image and reflecting a blue color image in the first direction and a red color image in the second direction; a first prism having therein a total reflection surface and an extended optical path length for reflecting the blue color image to a blue optical image-forming plane (I.sub.b); and a second prism having therein a total reflection surface and an extended optical path length for reflecting the red color image to a red optical image-forming plane (I.sub.r).
