ABSTRACT:
A dichroic color mixing flag for a multiparameter light is constructed that greatly improves the thermal shock tolerance of the flag and avoids having to use a more costly quartz substrate material. The dichroic color mixing flag may be substantially circular in shape. The dichroic color mixing flag may be fixed to a mechanical component so that the flag cannot rotate with respect to the mechanical component. The dichroic color mixing flag may be fixed to the mechanical component so that the mechanical component can move the dichroic color mixing flag without moving any other dichroic color mixing flag.
