摘要： A digital image projector includes a plurality of light modulation assemblies and a dichroic combiner. Each light modulation assembly includes at least one laser light source configured to provide an illumination beam, an optional a coated surface, and a spatial light modulator. If the coated surface is present, the respective laser light source is configured to direct the illumination beam to the coated surface, which directs the illumination beam toward the respective spatial light modulator. Otherwise, the respective laser light source is configured to direct the illumination beam directly toward the respective spatial light modulator. The spatial light modulator redirects output modulated light back to the coated surface, if present, and out of the corresponding light modulation assembly. The dichroic combiner directs the output modulated light from each of the plurality of light modulation assemblies toward a projection lens for projection onto a display surface.

摘要： An anti-reflective thin film coating formed on an optical surface, comprising a multilayer thin-film stack arranged to suppress reflection of incident polarized light within an incident light wavelength range. The multilayer thin-film stack further provides a reflectance edge transition at a wavelength band that lies outside the incident light wavelength range. The reflectance edge transition is arranged to provide phase difference compensation to the polarized light within the incident polarized light wavelength range.

摘要： A beam combiner for combining a plurality of light beams onto an optical path, comprising: a first dichroic element having a dichroic coating that is disposed to transmit light of a first wavelength band along the optical path and to reflect light of a second wavelength band onto the optical path, and a second dichroic element having a dichroic coating that is disposed to transmit the light of the first and second wavelength bands along the optical path and to reflect light of a third wavelength band onto the optical path. The beam combiner further includes a phase difference compensation multilayer thin-film stack that provides at least one reflectance edge transition that lies outside any of the first, second, and third wavelength bands and which provides compensation for an accumulated phase difference for polarization states of the transiting in at least one of the first, second, and third wavelength bands.
