Abstract
A color separating optical system including first to third prisms for separating incident light from an objective lens into three primary color light components, so as to project three color-separated images of a subject onto first to third image sensors, respectively. In order to prevent ghosts from being superposed on a center area of an image frame, the color separating optical system satisfies the condition: α≈(βm+βm+1)/2, wherein 'α' represents a tilt angle of a second dichroic film on the second prism to a perpendicular plane to an optical axis of the objective lens, and 'βm' a diffraction angle of the second light component diffractively reflected from the second image sensor and reentering the second prism.
