Abstract
In a color separating device, three reflection elements each formed by laminating a dichroic mirror and a total reflection mirror via a transparent layer interposed therebetween are used. The three reflection elements have mutually different spectral characteristics and are arranged to separate incident light reflected from a color original into three color lights without causing a difference in optical paths of the respective color lights. Two of the reflection elements may be used in combination with a condenser lens having principal points whose positions differ depending on wavelengths of light, so as to perform the three-color separation in a similar manner.
