摘要： A broadband wire grid polarizer for the visible spectrum has a plurality of elongated elements supported on a substrate. A region having a lower refractive index than the refractive index of the substrate is disposed between the elements and the substrate to reduce the longest wavelength at which resonance occurs. The region may comprise a plurality of ribs extending from the substrate and supporting the elements. The ribs may be formed by etching slots into the substrate using the elements as a mask. The region may also comprise at least one layer of dielectric film. In addition the region may be comprise ribs extending from the surface, each having at least one layer of dielectric film disposed thereon.

摘要： X-ray wave diffraction devices are constructed using atomic layer epetaxy. A crystalline substrate is prepared with one or more surface areas on which multiple pairs of layers of material are to be deposited. These layers are then formed by atomic layer epetaxy on the surface areas of the substrate, one on top of another, with the material of each layer of each pair being selected to have a different index of refraction from that of the material of the other layer of each pair. The layers are formed so that the thickness of each layer of a pair is substantially the same as that of the corresponding layer of every other pair and so that x-ray waves impinging on the layers may be reflected therefrom. Layer pairs having a thickness of about 20 angstroms or less are formed on the substrate.

摘要： A radiation detector window structure for use with a radiation detection system includes a frame, a plurality of upstanding spaced-apart ribs held in place by the frame, where the tops of the ribs terminate generally in common plane, and a thin film of material disposed on the tops of the ribs to span over the gaps therebetween for passing the radiation to be detected and for filtering at least some of the unwanted radiation. The tops of the ribs are smoothed and rounded to minimize a chance of piercing the film placed thereover. The ribs are spaced to provide sufficient support for the film so that the thickness of the film may be reduced to better transmit desired radiation.

摘要： A method of treating a substrate having first and second sides with corresponding oppositely facing first and second surfaces, to produce curvature in the first surface. The method includes the steps of removing material, according to a predetermined pattern, from the second side of the substrate, and applying a stress-producing film of material to at least one surface of the substrate to thereby cause the substrate to bend to produce the desired curvature in the first surface.
