A cube wire grid polarizer or an embedded wire grid polarizer can include an adhesive-free, direct bond between the wire grid polarizer and piece(s) of glass. Consequently, index of refraction mismatch can be avoided and the polarizer can have improved high temperature tolerance. The polarizer can include multiple layers over the wire grid polarizer, with the top of these layers polished, then directly bonded to the piece of glass. Material of the top layer can be selected such that thickness…

In one embodiment, an x-ray tube 15 can be used closer to a sample. An angle A1 between an anode axis 02 and an electron-beam axis 01 can be ≥10° and ≤80° and an angle A2 between the anode axis 02 and an x-ray axis 03 can be ≥10° and ≤80°. In another embodiment, a cap 20 on an anode 12 can block x-rays emitted in undesired directions. The cap 20 can include an internal cavity 24, an electron-beam hole 21, an anode hole 22, and an x-ray hole 23. In another embodiment, an electrical connection …

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, stretchability, compressibility, or comb…

Thick, inorganic coatings can be deposited on a polarizer by chemical vapor deposition. In one embodiment, the method can comprise activating a surface of the polarizer with an oxygen plasma in an oven; injecting a solution including tetrakis(dimethylamino)silane dissolved in cyclohexane and water into the oven; and vapor depositing silicon dioxide onto the polarizer. These three steps can be repeated multiple times until desired thickness is attained.

A wire grid polarizer (WGP) can be durable and have high performance. The WGP can comprise an array of wires 13 on a substrate 11. An overcoat layer 32 can be located at distal ends of the array of wires 13 and can span channels 15 between the wires 13. A conformal-coat layer 61 can coat sides 13s and distal ends 13d of the wires 13 between the wires 13 and the overcoat layer 32. The overcoat layer can comprise aluminum oxide. An antireflection layer 33 can be located over the overcoat layer 32.

A wire grid polarizer (WGP) can have low transmission of a primarily reflected/absorbed polarization (e.g. low Ts). The WGP can comprise an array of wires on a substrate and a stack of thin films between the substrate and the array of wires. The stack of thin films can include a first layer closest to the substrate, a second layer over the first layer, and a third layer over the second layer and closest to the array of wires. An index of refraction of the first layer can be greater than an in…

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…

An x-ray source can have a reduced voltage gradient and a consistent voltage gradient, thus allowing less insulation, reduced arcing failure, or both. The x-ray source can comprise a bipolar voltage multiplier and an x-ray tube. The bipolar voltage multiplier can include a negative voltage multiplier and a positive voltage multiplier. An axis extending from an input voltage of the negative voltage multiplier to a negative output bias voltage defines a negative axis. An axis extending from an …
