The ultra compact optical RGB multiplexer for a pocket projector that size is 8.8(W)×6.0(D)×4.0(H)(mm) was developed by the micro-molding processing. The RGB multiplexer was constructed by the optical filter and three lenses for each RGB laser diode in the molding packaging. The interface of the optical filter and the resin was not existed an air gap by optimizations of molding conditions. We were successfully projected onto a screen using the RGB multiplexer.
