Patent number: 10303067Abstract: The disclosure relates to a cooler for use in a device in a vacuum, wherein the partial pressure of the cooling medium in the vacuum environment during the operation of the cooler is less than 10?3 mbar. The cooler includes a heat sink, wherein a cavity through which the cooling medium flows is formed in the heat sink, and wherein the heat sink includes a connection element which surrounds one end of the cavity through which the cooling medium flows. The cooler also includes a connecting piece for joining a coolant line to the cavity. The connecting piece includes a jacket secured on the connection element by a thermal connecting process. An intermediate layer is between the jacket and the connection element.

Patent number: 7196842Abstract: An attenuating filter provides a prescribed attenuation of the intensity of transmitted, short-wavelength, ultraviolet light, in particular, at wavelengths below 200 nm, that is governed by a predefinable spatial distribution of its spectral transmittance. The filter has a transparent substrate (3), e.g. fabricated from crystalline calcium fluoride. A filter coating (5) fabricated from a dielectric material that absorbs over a predefined wavelength range is applied to at least one surface (4) of the substrate. In the case of operating wavelengths of about 193 nm, the filter coating consists largely of tantalum pentoxide. Filters of the type, which may be inexpensively fabricated with high yields, are noted for their high abilities to withstand laser radiation and may be effectively antireflection coated employing simply designed antireflection coatings.Type: GrantFiled: November 29, 2004Date of Patent: March 27, 2007Assignee: Carl Zeiss SMT AGInventors: Bernhard Weigl, Hans-Jochen Paul, Eric Eva
