摘要： Grids and collimators, for use with electromagnetic energy emitting devices, include at least a metal layer that is formed, for example, by electroplating/electroforming or casting. The metal layer includes top and bottom surfaces, and a plurality of solid integrated walls. Each of the solid integrated walls extends from the top to bottom surface and has a plurality of side surfaces. The side surfaces of the solid integrated walls are arranged to define a plurality of openings extending entirely through the layer. At least some of the walls also can include projections extending into the respective openings formed by the walls. The projections can be of various shapes and sizes, and are arranged so that a total amount of wall material intersected by a line propagating in a direction along an edge of the grid is substantially the same as another total amount of wall material intersected by another line propagating in another direction substantially parallel to the edge of the grid at any distance from the edge. Methods to fabricate these grids using copper, lead, nickel, gold, any other electroplating/electroforming materials, metal composites or low melting temperature metals are described.

摘要： A method of detecting fluorescence/absorbance/luminescence from 24-well, 48-well, 96-well, 384-well and 1536-well microplates and other sample containers. The sample is pumped into a waveguide. The waveguide efficiently gathers and guides the emission light to the end of the waveguide. The emission light exits the ends of the waveguide and is focused into a detector. To minimize background caused by the excitation light used for fluorescence, the excitation illuminates the waveguides at 90 degrees. To facilitate reuse, the waveguide assembly can be configured to be washed by an appropriate wash solution.

摘要： An apparatus and method for obtaining a high-resolution digital image of an object or objects irradiated with radiation having a wavelength in the x-ray or gamma ray spectrum generated by a radiation source, or of an object or objects emitting radiation within the x-ray or gamma ray spectrum. The apparatus comprises a detector matrix and a radiation mask. The detector matrix comprises a plurality of detector pixels, each comprising a detection surface having a respective surface area which generates a signal in response to an energy stimulus. The radiation mask has an opaque portion, and a plurality of apertures. The aperture size and position relative to the detector array determines the image resolution not the size of the detector pixels. The mask is positioned between the detector matrix and the radiation source, such that the opaque portion prevents portions of the radiation from passing through the mask, and each of the apertures permits a portion of the radiation which has passed through or has been emitted from a respective portion of the object to propagate onto an area of the detection surface, less than the surface area, of a respective one of the detector pixels. The signal from a large detector pixel or from a group of small detector pixels represent an image of the respective portion of the object. The detector matrix and radiation mask are moved in synchronism in relation to the object to enable the areas of the detection surfaces of the detector pixels to receive portions of the radiation propagating through or emitted from other portions of the object, and to output signals representative of those other portions. These steps of moving the detector pixels and mask and irradiating the object are repeated until digital images of all portions of the object have been obtained. Alternatively, the x-ray source can be moved to image all portions of the object. The images are then arranged into an image representative of the entire object.

摘要： The present invention is a device for producing collimated electron beams. The device comprises a gated field emission array having at least one emission tip and a grid electrode having a grid opening disposed above the emission tip in a first direction. The device also comprises an integrated planar lens electrode for producing a focusing effect on electron beams emitted by the emission tip. The planar lens electrode has a lens edge disposed aside at a distance from the grid opening in a second direction perpendicular to the first direction. Preferably, the planar lens electrode is an integrated layer with the gated field emission array on a substrate. The grid electrode and the lens electrode can be on the same layer and separated by a gap of vacuum. The planar lens electrode can be above the grid electrode, separated by an insulative material. Similarly, the planar lens electrode can be below the grid electrode, and separated by an insulator material. Sometimes, the base electrode on which the tips are formed can act as a lens.
