The sensitivity of the human eye to slight shifts in color balance, particularly in the blue-green and yellow-orange regions of the spectrum, necessitates careful control over all of the color-influencing parameters of a projection system. In a modern optical projection system, the dichroic coating of an integral reflector tungsten-halogen lamp may be the source of objectionable color imbalance. Despite rigorous manufacturing control, significant variations in spectral energy distribution of radiation reflected and transmitted from the dichroic coatings occur.
