x-ray microscope [′eks ‚rā ′mī·krə‚skōp] (engineering) A device in which an ultra-fine-focus x-ray tube or electron gun produces an electron beam focused to an extremely small image on a transmission-type x-ray target that serves as a vacuum seal; the magnification is by projection; specimens being examined can thus be in air, as also can the photographic film that records the magnified image. Any of several instruments which utilize x-radiation for chemical analysis and for magnification of 100-1000 diameters; it is based on contact or projection microradiography, reflection x-ray microscopy, or x-ray image spectrography.

| Jeffrey Gillow, a researcher at Brookhaven National Laboratory, has been making use of the X-ray microscope at the National Synchrotron Light Source (NSLS) in New York to see extremely fine details of bacteria biochemistry in a technique known as X-ray spectromicroscopy. Lamm, Measurements of wet metaphase chromosomes in the scanning-transmission x-ray microscope, Part 2, 3. The researchers hope to develop an X-ray microscope that will enable them to image cellular structures in three dimensions without having to stain or thin-slice samples. |
