6P? What does that mean? “P” stands for “primaries”, meaning the primary colors red, green, and blue. These are the colors of light that can be used to mix any other color. The reason for this is, that most humans have three kinds of light receptors (for photopic vision) that are responsible for the perception of these three colors. Three kinds of light receptors – so why then 6P and not 3P? The new technology of cinema projection uses six different wavelengths, two each in the blue, green and red range of the visible light spectrum. This is as such not anything special, INFITEC is based on this for more than a decade. What is special with 6P is the fact that these wavelengths are produced using lasers.
“Six different wavelength lasers are required for 3D”
For a year now there are devices in the market of cinema projection that are based on lasers as light sources. Call them laser projectors. In order to be compatible with INFITEC 3D, they are equipped with six different wavelength lasers, three for the left and right image, respectively. And why is this the future of cinema? The biggest cost issue in running a traditional cinema is… no, not the movies! It is the lamps, that wear very quickly and have to be replaced on a regular basis. Lasers are much more durable and promise fewer maintenance efforts. As lasers produce always exactly one wavelength there is no light that can not be used for 3D presentation – this is quite different from conventional projectors. And this is the reason why laser projectors are very bright with 3D content as well.
Currently, there is still a fly in the ointment: laser projectors are comparatively expensive. This will change with increasing sales numbers. Anyway: INFITEC can provide the appropriate 3D glasses, call them 6P glasses.
