    摘要: Systems and methods for performing photoreactions in a photoreactive material using scattered actinic light from at least one light-diffusing optical fiber are disclosed. The systems and methods include disposing a light-diffusing optical fiber relative to the photoreactive material. The light-diffusing optical fiber has a glass core, a surrounding cladding, and nano-sized structures situated either within the glass core or at the core-cladding boundary. The nano-sized structures are configured to scatter guided actinic light that travels in the light-diffusing optical fiber from an actinic light source. The scattered actinic light is provided throughout the photoreactive material and causes a photoreaction throughout the photoreactive material.

    摘要: A polarization switching apparatus has a first birefringent polarizer formed as a composite prism and disposed to direct incident light of a first polarization along a first optical path and light of a second polarization along a second optical path, wherein the second optical path is oblique to the first optical path. A beam redirector is disposed to redirect the first optical path from the first birefringent polarizer toward an input face of a second birefringent polarizer; wherein the second birefringent polarizer is also formed as a composite prism and is disposed to combine incident light of the first and second polarizations onto a common output path. A shutter apparatus is actuable to selectively block light of the first polarization or light of the second polarization from the input face of the second birefringent polarizer.

    摘要: An apparatus for providing a pulsed radiation beam has a radiation source providing a pulsed radiation beam at a constant pulse repetition frequency. A beam deflector in the path of the pulsed radiation beam is actuable to redirect the pulsed radiation beam cyclically towards each of a plurality of beam intensity modulators in turn. A beam recombiner combines modulated light from each of the plurality of beam intensity modulators in order to form the modulated pulsed radiation beam at the constant pulse repetition frequency.

    摘要: The illumination of a photolithographic projection imager is given a variable annular intensity profile by using diverging and counter diverging elements that are movable relative to each other in the illumination path. An upstream element diverges the illumination into an annular configuration, the radius of which is set by the distance downstream to the counter diverging element. Convex and concave conical surfaces on the movable elements can accomplish this.

    摘要: The present disclosure is directed to a method for determining the state of cleanliness of an optical component (an optic) before any coating is applied to the surface. In method is particularly applicable to optical elements and components that are intended for uses in the DUV (deep ultraviolet) and EUV (extreme ultraviolet) wavelength regions. The disclosure combines a cleaning procedure with contamination metrology utilizing a spectrometer to provide a method that will determine the state of cleanliness of the component surface by measurement of the fluorescence spectrum of the optic and comparing the measured value with a standard or reference optic of known, acceptable cleanliness. The disclosure is further directed to an optic having a selected coating thereon that is formed according to the method described herein.
