  • Patent number: 11520087
    Abstract: Reflective optical element with extended service life for VUV wavelengths includes a substrate (41) and a metal layer (49) thereon. At least one metal fluoride layer (43) on the metal layer faces away from the substrate and at least one oxide layer (45) on the metal fluoride layer faces away from the substrate. The thicknesses of the layers on the metal layer facing away from the substrate are selected so that the electrical field of a standing wave, formed when a relevant wavelength is reflected, has a minimum in the region of the oxide layer. In addition, the relevant wavelength is selected so that, from a minimum VUV wavelength range to the relevant wavelengths, the integral over the extinction coefficients of the material of the at least one oxide layer is between 15% and 47% of the corresponding integral from the minimum wavelengths to a maximum wavelength.

  • Patent number: 11454806
    Abstract: A camera having a heating arrangement comprising a heater arranged to supply heat to a window. A thermally conductive member is arranged in contact with a housing and with the heating arrangement, when a temperature at the conductive member is below a threshold, to transfer heat supplied by the heater to the housing. A thermally insulating member is arranged in proximity with the housing and the heating arrangement. The conductive and/or insulating member is configured to, when the temperature increases above the threshold during heater operation, change its extension to enable contact between the insulating member and the housing and between the insulating member and the heating arrangement, and to disable contact between the conductive member and the housing and between the conductive member and the heating arrangement, thereby thermally insulate the housing from the heater.
