Method for manufacturing a selective light splitter and recombining device that divides white light into red, green and blue light and recombines red, green and blue light independently of polarization, provides two coating systems, each reflecting and transmitting color-selectivity. A transparent base body is embedded in or is on the coating systems and at least one of the coating systems has a layer of a material with lower refractive index and at least one of a material with higher refractive index. The lower refractive index is selected so that 1.7<=NLS<=2.1 and the refractive index of the transparent base body is selected so that 1.52>=NK>=1. The method also includes determining an emergent face for the red, green and blue light, and tilting one emergent face such that it forms an angle phi deviating from zero by more than is caused by fabrication tolerances for which phi<=5°.
