design, you get stable, consistent color under all viewing conditions, in addition to high optical efficiency.

In addition, the Sony 4K projectors mount the SXRD panels into optical engines that provide almost precisely equal length for the Red, Green and Blue beams. This feature also helps provide consistent, natural color.

This schematic view of the Sony 4K light engine shows the three SXRD panels and the nearly equal-length optical paths for Red, Green and Blue.

This simplified rendering shows the SXRD panels, Main PBS blocks and the final Cross Dichroic Prism, where the three colors combine.
