Let us come to wavelength multiplex 3D (WMT). This is known to work well with conventional light sources though a lot of light is lost in the filters required. When the emission bands of the primary colors red, green, and blue are narrower but not too narrow to be split into two bands each, the efficiency of a WMT 3D system will increase. This is the case for LED light sources. With laser projectors we have got a problem: Laser lines are so narrow, they cannot be divided into two that can be separated by any kind of filters. The solution for pure laser projectors is simple but costly: double the number of wavelengths used in order to get two blues, two greens, and two reds, one of each for the left image and one for the right one. This technique is called 6P for six primaries and is extremely light efficient. In addition, INFITEC offers lightweight glasses with unbreakable film lenses for these projection systems.
