    Abstract: A source-collector device is constructed and arranged to generate a radiation beam, The device includes a target unit constructed and arranged to present a target surface of plasma- forming material; a laser unit constructed and arranged to generate a beam of radiation directed onto the target surface so as to form a plasma from said plasma-forming material; a contaminant trap constructed and arranged to reduce propagation of particulate contaminants generated by the plasma; a radiation collector comprising a plurality of grazing-incidence reflectors arranged to collect radiation emitted by the plasma and form a beam therefrom; and a filter constructed and arranged to attenuate at least one wavelength range of the beam.

    Abstract: A spectral purity filter includes a body of material, through which a plurality of apertures extend. The apertures are arranged to suppress radiation having a first wavelength and to allow at least a portion of radiation having a second wavelength to be transmitted through the apertures. The second wavelength of radiation is shorter than the first wavelength of radiation. The body of material is formed from tungsten-molybdenum alloy or a molybdenum-rhenium alloy or a tungsten-rhenium alloy or a tungsten-molybdenum-rhenium alloy.

    Abstract: A reflector includes a multi layer mirror structure configured to reflect radiation at a first wavelength, and one or more additional layers. The absorbance and refractive index at a second wavelength of the multi layer mirror structure and the one or more additional layers, and the thickness of the multi layer mirror structure and the one or more additional layers, are configured such that radiation of the second wavelength which is reflected from a surface of the reflector interferes in a destructive manner with radiation of the second wavelength which is reflected from within the reflector.
