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: Polarizing optical devices described herein, and polarizing optical devices resulting from methods described herein, can be small and can have high heat tolerance. Wires of wire grid polarizers can be attached directly to prisms of the polarizing optical devices, allowing for small size. Multiple polarizing optical devices can be attached by adhesive-free bonding techniques, allowing high heat tolerance.

Abstract: A wire grid polarizer can have a protective-layer PL on each wire 12 sidewall SW. The protective-layer PL can protect the sidewall SW from corrosion, oxidation, or both. The protective-layer PL can be absent from or thinner at a distal-end DE of the wire 12, farther from the substrate. Polarizer performance degradation, from the protective-layer PL, can be minimized or eliminated by removing the protective-layer PL from the distal-end DE. The invention is particularly applicable to a wire grid polarizer with multiple layers UL and LL, and the upper-layer UL at the distal-end DE is more resistant to corrosion and oxidation than the embedded lower-layer LL.

Abstract: A wire grid polarizer (WGP) can include an array of support-ribs on a substrate. Sides of the support-ribs can be inclined to one side. A wire can be applied on an upper-side and distal end of each support-rib, each wire being separate from wires on adjacent support-ribs. The WGP can be made with reduced or no etching.

Abstract: An x-ray window can include a thin film that comprises boron. The thin film can be relatively thin, such as for example ≤200 nm. This x-ray window can be strong; can have high x-ray transmissivity; can be impervious to gas, visible light, and infrared light; can be easy of manufacture; can be made of materials with low atomic numbers, or combinations thereof. The thin film can include an aluminum layer. A support structure can provide additional support to the thin film. The support structure can include a support frame encircling an aperture and support ribs extending across the aperture with gaps between the support ribs. The support structure can also include boron ribs aligned with the support ribs.

Abstract: A shield around an x-ray tube, a voltage multiplier, or both can improve the manufacturing process by allowing testing earlier in the process and by providing a holder for liquid potting material. The shield can also improve voltage standoff. A shielded x-ray tube can be electrically coupled to a shielded power supply.

Abstract: A wire grid polarizer (WGP) can include a flexible substrate. The flexible substrate might be desirable for WGP flexibility or to aid in further processing of the WGP. Wires of the WGP can include flexible ribs to minimize or avoid defects such as cracks in the WGP. An etch stop layer in the wires can allow formation of the flexible ribs without delamination of a reflective portion of the wires. The WGP embodiments herein can have improved flexibility, stretchablility, compressibility, or combinations thereof with reduced cracking, collapse, and delamination of wires or ribs.

Abstract: It would be advantageous to reduce weight and size of high voltage power supplies, to increase frequency of pulses of high voltage, and to improve control of magnitude of high voltage. The embodiments of high voltage power supplies described herein can solve these problems. The high voltage power supply can be used with an x-ray tube. The high voltage power supply can comprise an array of planar transformers each defining a stage with an AC input and a DC output. Each stage can comprise a pair of flat, coil windings adjacent one another and including a primary winding electrically-coupled to the AC input and configured to induce a current in a secondary winding. At least two stages can be electrically-coupled together in series with the DC output of one stage electrically-coupled to an input of the other stage such that a voltage is amplified across the stages.

Abstract: An x-ray tube anode can include an electron hole extending from an electron entry at an exterior of the anode into a core of the anode, and an x-ray hole extending from an x-ray exit at the exterior of the anode into the core of the anode. The x-ray hole can intersect the electron hole at the core of the anode. In one embodiment, the electron hole and the x-ray hole can form a seamless bore from the electron entry to the x-ray exit. In another embodiment, the anode can be a single, integral, monolithic material with a single bore extending therethrough. In another embodiment, the core of the anode can include a target material located at a concave wall of the core of the anode.
