    Abstract: An optical device includes a stack that includes a first curved optical element stacked with a second curved optical element. The second curved optical element propagates light by total internal reflection. The stack also includes an incoupling diffractive grating that incouples the light into the second optical element and an outcoupling diffractive grating optically coupled to the incoupling diffractive grating through the second curved optical element. The outcoupling diffractive grating directs the light. The first curved optical element has a first refractive index, the second curved optical element has a second refractive index, and the first refractive index is different from the second refractive index by approximately 0.15 to 1.2.

    Abstract: A system for disinfecting a medical device is provided. The system includes a light source that generates light having at least one wavelength between about 100 nm and about 500 nm. The system further includes at least one cylindrical optical diffuser disposed in optical communication with at least one interior channel of a medical device, the at least one cylindrical optical diffuser having an outer surface and an end optically coupled to the light source. The at least one cylindrical optical diffuser is configured to scatter guided light through the outer surface to form a light diffuser portion having a length that emits substantially uniform radiation over its length.

    Abstract: The disclosure is directed to multilayer Mo/Si coatings for reflective mirrors used in extreme ultraviolet lithographic systems and to a method of making such mirrors using plasma ion assisted deposition (PIAD) techniques. The coating are deposited on a substrate suitable for EUV lithography, and are Mo/Si coating consisting of 40-100 Mo/Si periods, each period consisting on a Mo layer followed by a Si layer. Each of the individual Mo and Si layers is deposited to a specified or target thickness in the range of 2 nm to 5 nm, and the thicknesses are controlled to ±0.1 nm. A plasma from a plasma source is used to densify and smooth the substrate prior to deposition of the coating, and each layer of the coating is plasma densified and smoothed.

    Abstract: The disclosure is directed to a coating consisting of a binary metal fluoride coating consisting a high refractive index metal fluoride layer on top of a substrate, a low refractive index metal fluoride layer on top of the high refractive index layer and layer of SiO2 or F—SiO2 containing 0.2 wt % to 4.5 (2000 ppm to 45,000 ppm) F on top of the low refractive index layer. In one embodiment the F content of F—SiO2 is in the range of 5000 ppm to 10,000 ppm F. The high index and low index materials are each deposited to a thickness of less than or equal to 0.9 quarter wave, and the capping material is deposited to a thickness in the range of 5 nm to 25 nm. The disclosure is also directed to optical elements having the foregoing coating and a method of making the coating.
