ABSTRACT:
An apparatus for separating an incident light beam from a light source into three light beams having different colors by a mirror mechanism constructed in a particular way. The apparatus separates white-light into three colors of red, green, and blue and includes a first dichroic mirror, a wide band high-reflection mirror, a second dichroic mirror, and a material of air or gas. The first dichroic mirror allows only a light beam with a first wavelength to penetrate and reflects light beams with other wavelengths, from the incident light beam. The wide band high-reflection mirror reflects the light beam reflected from the first dichroic mirror within the material, and is positioned such that it is parallel to the first dichroic mirror and is spaced therefrom by a predetermined interval. The second dichroic mirror allows only a light beam with a second wavelength different from the first wavelength to penetrate in a direction that is parallel to the light beam with the first wavelength penetrated through the first dichroic mirror and reflects a light beam with a third wavelength different from the first and second wavelengths within the material. The wide band high-reflection mirror reflects the light beam which is reflected from the second dichroic mirror within material and then the reflected light beam with the third wavelength passes outside the material past the second dichroic mirror in a direction that is parallel to the light beam with the second wavelength penetrated through the second dichroic mirror. The material of air or gas is positioned between the first, second dichroic mirrors and the wide band high-reflection mirror, through which the incident light beam and the reflected light beams proceed.
