摘要:
A zone plate includes a plurality of consecutively arranged, adjacent, and alternating first and second regions. The first regions are arranged to be substantially transparent to a first predetermined wavelength of radiation and a second predetermined wavelength of radiation that is different from the first predetermined wavelength of radiation. The second regions are arranged to be substantially opaque, diffractive, or reflective to the first predetermined wavelength of radiation and substantially transparent to the second predetermined wavelength of radiation.

A spectral purity filter includes an aperture. The spectral purity filter is configured to enhance the spectral purity of a radiation beam by being configured to absorb radiation of a first wavelength and allow at least a portion of radiation of a second wavelength to transmit through the aperture. The first wavelength is larger than the second wavelength. The spectral purity filter may be used to improve the spectral purity of an Extreme Ultra-Violet (EUV) radiation beam.

The present invention relates to a compartment provided a tufted textile (100) comprising: a backing (10), and yarns (40) forming tufts extending from a first side of the backing, the compartment further comprising a light source (50; 80) and a conductor arrangement (60) for the light source, wherein the light source, the conductor arrangement and the backing are arranged so as to radiate light from the light source at least partly through the backing, the backing being substantially permeable to light. The tufted textile (100) may be a carpet.
摘要:
A light output device comprises a power supply and a plurality of light source device arrangements arranged in a line extending from a power connection, with adjacent light source device arrangements in the line connected together with an electrical connector arrangement. Each light source device arrangement is associated with a control circuit from the plurality of control circuits for providing independent control of the light source device arrangement output based on the control signal. The device can be reduced in length by disconnecting the connector arrangement between an adjacent pair of light source device arrangements and the remaining light source device arrangements extending from the power source are independently controlled by the control signal.

The invention relates to a self-cleaning system (10) and window glass. The self-cleaning system comprises a translucent substrate (20), a light-emitting device (30) and a photo-catalytic layer (40) applied to a surface (22) of the translucent substrate for generating a self-cleaning surface. The photo-catalytic layer produces the self-cleaning effect when illuminated with light of a predefined wavelength range. The translucent substrate is translucent for at least a sub-range of the predefined wavelength range. The light-emitting device is arranged for illuminating the photo-catalytic layer via the translucent substrate, an emission spectrum emitted by the light-emitting device comprising light within the sub-range. The effect of the illumination system according to the invention is that the illumination of the photo-catalytic layer via the translucent substrate enables the light-emitting device to be arranged relatively near to the photo-catalytic layer such that only a relatively low light flux is required from the light-emitting device to activate the self-cleaning process.
摘要:
A debris prevention system is constructed and arranged to prevent debris that emanates from a radiation source from propagating with radiation from the radiation source into or within a lithographic apparatus. The debris prevention system includes an aperture that defines a maximum emission angle of the radiation coming from the radiation source, and a first debris barrier having a radiation transmittance. The first debris barrier includes a rotatable foil trap. The debris prevention system also includes a second debris barrier that has a radiation transmittance. The first debris barrier is configured to cover a part of the emission angle and the second debris barrier is configured to cover another part of the emission angle.
摘要:
A radiation source for generating electromagnetic radiation includes an anode, a cathode, and a discharge space. The anode and the cathode are configured to create a discharge in a substance in the discharge space to form a plasma so as to generate the electromagnetic radiation. The radiation source also includes a fuel supply constructed and arranged to supply at least a component of the substance to a location near the discharge space. The fuel supply is located at a distance from the anode and the cathode. The radiation source also includes a further supply constructed and arranged to create and/or maintain a cooling and/or protective layer on or near the anode and/or cathode.
