Two dichroic mirrors for both red-reflecting and blue-reflecting lights are utilised for dividing illumination light in the optical projection system. Furthermore, an X-cube is also adopted as a light combining prism in the optical projection system.

The coatings make the same wavelength drift of spectrum for both P and S polarised lights between the dichroic mirrors and the X-cube. This achieves high transparency ratio and improves illumination efficiency with lower cost.
