A WGP 10 can include an array of parallel, elongated rods 14 located over a surface of a transparent substrate 11 with gaps 15 between adjacent rods 14. Each of the rods 14 can include a reflective wire 13 sandwiched between ribs 12. One of the ribs 12 can be a transparent rib and one can be an absorptive rib. The WGP 10 can have high efficiency and high contrast for light entering on the transparent rib side and low Rs for light entering on the absorptive rib side.


A transmission x-ray tube comprising an end window hermetically sealed to a flexible coupling. The flexible coupling can allow the window to shift or tilt in one direction or another direction to allow an electron beam to impinge upon one region of the window or another region of the window. A method of utilizing different regions of an x-ray tube target by tilting an x-ray tube window at an acute angle with respect to an electron beam axis to cause an electron beam to impinge on a selected region of the window and tilting the window in a different direction to allow the electron beam to impinge on a different selected region of the window.

Cube polarizers can be designed for substantially equal optical path lengths of a reflected beam and a transmitted beam. For example, d_(11 )of FIG. 1 can define a distance between a plane (face plane_(2)) of the outer face (outer face_(2)) of a second prism 16 and the first edge (first edge_(1)) of the first prism, and d_(11 )can be less than 400 micrometers. As another example, an optical path length differential between a transmitted beam and a reflected beam (|OPL_(T)OPL_(R)|) can be where t is a thickness of the substrate between the first surface and the second surface of the substrate and n_(P )is an index of refraction of the first prism.

An XRF analyzer (10) can include a rotatable filter structure (15) to separately position at least two different x-ray source modification regions (15s) between an x-ray source (12) and a focal point (F) and at least two different x-ray detector modification regions (15d) between an x-ray detector (11) and the focal point. An XRF analyzer (70) can include a rotatable source filter wheel (12w) between an x-ray source (12) and a focal point (F) and a rotatable detector filter wheel (11w) between an x-ray detector (11) and the focal point. The source filter wheel can include multiple x-ray source modification regions (15s). The detector filter wheel can include multiple x-ray detector modification regions (15d). A gear wheel (76g) can mesh with a gear on the source filter wheel and with a gear on the detector filter wheel and can cause the source filter wheel and the detector filter wheel to rotate together.

An electrostatic dissipation device 10 can comprise an elongated enclosure 11 with a longitudinal axis 12. An x-ray source 13 can be oriented to emit x-rays 16 inside of and along the longitudinal axis 12. A fluid-flow device 14 can be oriented to cause fluid to flow across the x-ray source 13 then inside of and along the longitudinal axis 12, the fluid being ionized by the x-rays 16, forming ionized fluid, then out of the elongated enclosure through outlet opening(s) 15. The arrangement of the x-ray source 13 and the fluid-flow device 14 can allow (1) fluid from the fluid-flow device 14 to cool the x-ray source 13, and (2) ion generation along the length of the elongated enclosure 11.
