摘要: A projection system for generating an image with three primary colors, comprising a first and second blue laser beam (325, 335), a wavelength conversion element (340) for converting said second blue beam (335) into a converted beam (345) having a waveband comprising at least the second and third wavebands, a beam combiner (360) for combining the first beam (325) and the converted beam (345), which combination results in a white beam (365), a notch filter (370) placed in the optical path of the white beam (365) to form a modified white beam (375) comprising at least the first, second and third wavebands provided to an imaging module (380), wherein a static waveband reduction filter (371) is further provided for changing the wavelength of transmitted second waveband of the white beam (365), such as to adjust a projector white point shift.
