Abstract
A composite light dividing device is provided. The composite light dividing device receives a light beam mixed by lights of at least two wavebands. The composite light dividing device includes a refracting/diffracting unit, and a refracting unit. The refracting/diffracting unit is adapted for receiving the light beam and condensing the light beam into a condensed light beam, and dividing the condensed light beam at a deflection direction to obtain the lights of the wavebands. The refracting unit is adapted for deflecting the divided lights of the wavebands for outputting them from a specific direction. The composite light dividing device for example can be used in an image apparatus, and the divided lights of the wavebands can serve as primary color lights of the pixel colors.
