Abstract:
An all-reflective optical system, comprising:an entrance region coincident with an optical reference axis;an exit region coincident with the optical reference axis;a dichroic beam splitter assembly coincident with the optical reference axis, the dichroic beam splitter assembly includingan entrance dichroic beam splitter positioned to receive radiation passing through the entrance region, andan exit dichroic beam splitter positioned to direct radiation through the exit region;a first beam processing array having a first array input beam of a first wavelength range reflected from the entrance dichroic beam splitter and a first array output beam of the first wavelength range directed to the exit dichroic beam splitter so as to be reflected through the exit region; anda second beam processing array having a second array input beam of a second wavelength range transmitted through the entrance dichroic beam splitter and a second array output beam of the second wavelength range transmitted through the exit dichroic beam splitter to the exit region.
