Publication number: 20220229307Abstract: A spectrally-shaped source includes a source that generates a round beam. An optical element transforms the round beam to a rectangular beam. An image forming dispersive device angularly disperses wavelengths and images the rectangular beam at a modulation plane. A pixelated SLM is illuminated by the dispersed wavelengths of the rectangular beam such that each column of illuminated pixels is illuminated by a different wavelength. Toroidal optics projects light directed from the SLM to an output plane and focuses the angularly dispersed wavelengths of the beam so that a selected portion of the optical beam is reflected toward the toroidal optic by the SLM. A controller instructs the pixelated SLM to selectively reflect the portion of the optical beam toward the toroidal optic and to selectively reflect another portion of the beam away from the toroidal optic so as to provide a desired spectral shape.Type: ApplicationFiled: January 17, 2022Publication date: July 21, 2022Applicant: Hamamatsu Photonics K.K.Inventors: Qingsong Wang, Kosuke Saito, Alexander Cutler, Jonathan P.

Publication number: 20070188061Abstract: A high intensity discharge lamp is provided with an arc tube having an improved heat insulator. The heat insulator is formed proximate to at least one end of the arc tube but absent around an outer middle portion of the arc tube. In addition, the heat insulator is made of a material transmissive of visible light but not transmissive of thermal radiation. By adding a heat insulator to the cold spot area of the arc tube, radiation heat lose from that area will be significantly reduced and the temperature of that area will be increased. Moreover, by choosing a material that will not get oxidized and will not block the visible light, higher lamp efficacy can be achieved.Type: ApplicationFiled: February 15, 2006Publication date: August 16, 2007Inventor: Huiling Zhu
