Abstract
An optical device comprises a light source unit comprising a plurality of light sources, a light mixing unit that is formed on the light source unit and comprises a light guiding part guiding light emitted from each light source, and a light mixing part mixing the guided light. A supporter supports the light mixing unit to be spaced from the light source unit. A small-sized optical device is provided having an enhanced light efficiency and a projection system having the same.
