Abstract: A reflective spatial light modulator array is described incorporating liquid crystal devices, mirrors, a semiconductor substrate, electrical circuits, and a reflector/absorber layer for blocking light. The invention overcomes the problem of shielding light from semiconductor devices, high optical throughput and contrast, pixel storage capacitance to hold the voltage across the liquid crystal device and precise control of the liquid crystal device thickness without spacers obscuring the mirrors.

Abstract: Optical elements, and methods for fabricating them, are described wherein each element includes a free standing (self supporting) polycrystalline continuous thin film of diamond (101) combined with a non-hydrogenated amorphous diamond like carbon (DLC) film having a high percentage of sp bonding (104). These elements may be designed to have optically smooth surfaces, have wide optical transmission ranges (for example, be transparent across the infrared portion of the spectrum), and exhibit exceptional durability characteristics. Optical instruments that include such elements are also described, along with the derivative benefits, such as improved operating performance and lower maintenance requirements, realized using the novel optical elements. In particular, a polarization Michaelson interferometer (PMI) is taught which is operative over the entire range from far infrared into the visible portion of the spectrum without requiring the exchange of beam splitters or beam polarizers. These performance benefits are achieved as a result of the transmission characteristics of the novel optical elements associated with the PMI.

Abstract: A spherical grid for use in instrumentation comprising a rigid non-magnetic frame (10) having a pattern of holes (16). Into each hole a flat wafer (20) is placed, each wafer having etched therein holes defining the grid mesh. The frame maintains the geometric conformal shape allowing large units to be constructed.

Abstract: The present invention provides an ion beam system which produces an ion beam pattern without the need for a mask. A programmable grid (35) is used in combination with an ion beam source (14), where the apertures (54, 56, 68) of the programmable grid (35) can have electrical potentials associated therewith which either extract ions or impede the movement of ions through the apertures (54,56, 68). Depending upon the electrical biasing provided to each of the apertures (54, 56, 68) of the grid (35), different patterns of ions can be extracted through the grid (35). By changing the electrical bias at different locations on the programmable grid (35), these different patterns are produced. The patterns can be used for many applications including patterned deposition, patterned etching and patterned treatment of surfaces.
