Abstract: A collimator for an x-ray tube can be a monolithic, integral structure. The collimator can include a proximal-end closest to a cathode and a distal-end farthest from the cathode. The proximal-end can adjoin a vacuum inside of the x-ray tube. The distal-end can adjoin the air. The collimator can include an aperture extending therethrough. An x-ray window can be mounted across the aperture. The aperture can include a collimation-region between the x-ray window and the distal-end, and a drift-region between the x-ray window and the proximal-end. X-rays can be generated inside of the collimator.

Abstract: An x-ray window can include an adhesive layer sandwiched between and providing a hermetic seal between a thin film and a housing. The adhesive layer can include liquid crystal polymer. The liquid crystal polymer can be opaque, gas-tight, made of low atomic number elements, able to withstand high temperature, low outgassing, low leakage, able to relieve stress in the x-ray window thin film, capable of bonding to many different materials, or combinations thereof.

Abstract: A planar filament 11f can include multiple materials to increase electron emission in desired directions and to suppress electron emission in undesired directions. The filament 11f can include a core-material CM between a top-material TM and a bottom-material BM. The top-material TM can have a lowest work function WFt; the bottom-material BM can have a highest work function WFb; and the core-material CM can have an intermediate work function WFc (WFt Wb). This shape makes it easier to coat the edges 31e with the bottom-material BM, because the edges 31e tilt toward and partially face the sputter target. This shape also helps direct more electrons to a center of the target 14, and reduce electron emission in undesired directions.

Abstract: An x-ray detector can be small and have efficient cooling. In one embodiment, the x-ray detector can comprise a thermoelectric cooler (TEC) with upper electrical connections, a support, a cap, and a silicon drift detector (SDD). A planar side of the support can be directly affixed to upper electrical connections of the TEC. The support can have a non-planar side, opposite of the planar side, with a raised structure. A bottom face of the cap can be affixed to the raised structure, forming a cavity between the cap and the non-planar side of the support. The SDD can be affixed to a top face of the cap. In another embodiment, the non-planar side of the support can face the TEC. In another embodiment, a PIN photodiode can be directly affixed to a plate and the plate directly affixed to upper electrical connections of the TEC.

Abstract: A reflective wire grid polarizer (WGP) can include an array of wires 12 on a face of a substrate 11, with channels 15 between adjacent wires 12. The wires 12 can have certain characteristics for WGP performance, such as index of refraction, alternating high/low index continuous thin films, thickness of layer(s), duty cycle, reflective rib shape, a curved side of transparent ribs 21 or 32, aspect ratio, or combinations thereof.

Abstract: An optical device can comprise wires 12 on a face of a substrate 11, with channel(s) 13 between adjacent wires 12. Each wire 12 can include embedded organic moieties. Each wire 12 can include multiple ribs 31. Part or all of the wire 12, the substrate 11, or both can have a high refractive index n and a low extinction coefficient k. The optical device can have reduced separation of layers of different materials during flexing and temperature changes. The optical device can be manufactured by a method designed for improved manufacturability.

Abstract: Optical devices with different regions or pixels can form an image. An opaque-region 14 can be used to separate different pixels. Sometimes the optical device needs to be flexible, for elongation or stretching onto a curved surface. But, the opaque-region 14 can be damaged as it is stretched. A flexible optical device can include a modified opaque-region 14 for improved flexibility. The opaque-region 14 can include a thin-film 12 with multiple cavities 13, multiple zones 63, or both. Each zone 63 can have a shape optimized to both block incoming light and for flexibility. Each zone 63 can be encircled and separated from adjacent zones 63 by a groove 62. The cavities 13 and the separate zones 63 can allow the opaque-region 14 to bend or stretch without cracking or delamination of the thin-film 12.
