A wire grid polarizer (WGP) can have a conformal-coating to protect the WGP from oxidation and/or corrosion. The conformal-coating can include a barrier layer with at least one: of aluminum oxide, silicon oxide, silicon nitride, silicon oxynitride, silicon carbide, hafnium oxide, and zirconium oxide. A method of making a WGP can include applying the barrier layer over ribs of a WGP by vapor deposition.

A wire grid polarizer (WGP) can have a conformal-coating to protect the WGP from at least one of the following: corrosion, dust, and damage due to tensile forces in a liquid on the WGP. The conformal-coating can include a silane conformal-coating with chemical formula (1), chemical formula (2), or combinations thereof: A method of applying a conformal-coating over a WGP can include exposing the WGP to Si(R^(1))_(d)(R^(2))_(e)(R^(3))_(g). In the above WGP and method, X can be a bond to the ribs; each R^(1 )can be a hydrophobic group; each R^(3), if any, can be any chemical element or group; d can be 1, 2, or 3, e can be 1, 2, or 3, g can be 0, 1, or 2, and d+e+g=4; R^(2 )can be a silane-reactive-group; and each R^(6 )can be an alkyl group, an aryl group, or combinations thereof.

A wire grid polarizer comprising on array of parallel, elongated first rib groups disposed over a substrate. Each first rib group can comprise a central first transmissive rib and a pair of first wires including a first wire disposed along each side of the first transmisslve rib. A first dielectric material can substantially fill first gaps between each rib group and an adjacent rib group. An array of parallel, elongated second wires can be disposed over the rib groups and the first dielectric material. The first wires or the second wires can be absorptive and the other of the first wires or the second wires can be reflective.

An embedded, inverse wire-grid polarizer (WGP) includes ribs 13 located over a surface of a transparent substrate 11, gaps 16 between the ribs 13, and a fill-layer 15 substantially filling the gaps 16. The fill-layer has a relatively high index of refraction, such as greater than 1.4. At a wavelength of light incident upon the WGP, E_() transmission can be greater than E_() transmission. E_() is a polarization of light with an electric field oscillation parallel to a length L of the ribs, and E_() is a polarization of light with an electric field oscillation perpendicular to a length L of the ribs. This embedded, inverse WGP is especially useful for polarizing, with high WGP performance, small wavelength (high-energy) regions of the electromagnetic spectrum (e.g. UV) which are difficult to polarize with conventional WGPs (E_() transmission>E_() transmission).

The invention includes a power supply 17 for an x-ray tube 49. The power supply 17 can comprise a control box 48 and a remote box 47. An electron-emitter transformer 14 can be located in the remote box 47. A box-connector cable 41 between the control box 48 and the remote box 47 can be relatively long and an x-ray tube cable 21 between the remote box 47 and an electron emitter 19 can be relatively short. This design can provide improved electrical power transfer from the power supply 17 to the x-ray tube 49. Also, electrical cable size and cost can be reduced if a high voltage source 15 is located in the remote box 47.

Embodiments of a chemical, methods of applying a chemical, and devices with a coating of a chemical can be used to protect devices from harm, such as for example corrosion, water tensile forces, dust, and oxidation. The device can include a phosphonate-coating, a silane-coating, or both, located on a substrate. The silane-coating can include chemical formula (1), chemical formula (2), or combinations thereof; and the phosphonate-coating can include chemical formula (3): where R^(1 )can be a hydrophobic group; R^(3 )and R^(5 )can be any chemical element or group; r can be a positive integer; and X and Z can each be a bond to the substrate.

A wire grid polarizer (WGP) can have a phosphonate conformal-coating to protect the WGP from at least one of the following: corrosion, dust, and damage due to tensile forces in a liquid on the WGP. The conformal-coating can include a chemical: where R^(1 )can include a hydrophobic group, Z can be a bond to the ribs, and R^(5 )can be any suitable chemical element or group. A method of applying a phosphonate conformal-coating over a WGP can include exposing the WGP to (R^(1))_(i)PO(R^(4))_(j)(R^(5))_(k), where: i is 1 or 2, j is 1 or 2, k is 0 or 1, and i+j+k=3; each R^(1 )can independently be a hydrophobic group; R^(4 )can be a phosphonate-reactive-group; each R^(6 )can independently be an alkyl group, an aryl group, or combinations thereof; and each R^(5), if any, can independently be any suitable chemical element or group.

The invention includes an XRF analyzer with reduced x-ray attenuation between sample and target and between sample and detector. Attenuation can be reduced by removing atmospheric-air paths through which the x-rays must travel. Reduced x-ray attenuation can allow for easier detection of low-atomic-number elements. Cost saving can be achieved by reducing the number of x-ray windows.
