ABSTRACT:
A composite optical dividing device can receive a light beam, which is mixed with at least multiple wavelength ranges of light. The optical dividing device includes a first optical film plate and a second optical film plate. The first optical film plate has multiple micro-structure lenses in same shape, for deflecting and the incident light with a condense level. The second optical film plate has multiple periodic polygon structures, for receiving the deflected light and dividing constitutions of the light beam, according to the wavelength ranges. Each of the multiple ranges of light respectively travels toward a predetermined region on a plane.
