x-ray microscope

microscope

[mi´kro-skōp] an instrument used to obtain an enlarged image of small objects and reveal details of structure not otherwise distinguishable.

The light path of a darkfield microscope. From Hart and Shears, 1997.acoustic microscope one using very high frequency ultrasound waves, which are focused on the object; the reflected beam is converted to an image by electronic processing.binocular microscope one with two eyepieces, permitting use of both eyes simultaneously.compound microscope one consisting of two lens systems whereby the image formed by the system near the object is magnified by the one nearer the eye.darkfield microscope one so constructed that illumination is from the side of the field so that details appear light against a dark background.electron microscope one in which an electron beam, instead of light, forms an image for viewing, allowing much greater magnification and resolution. The image may be viewed on a fluorescent screen or may be photographed. Types include scanning and transmission electron microscopes.fluorescence microscope one used for the examination of specimens stained with fluorochromes or fluorochrome complexes, e.g., a fluorescein-labeled antibody, which fluoresces in ultraviolet light.light microscope one in which the specimen is viewed under ordinary illumination.operating microscope one designed for use in performance of delicate surgical procedures, e.g., on the middle ear or small vessels of the heart.phase microscope (phase-contrast microscope) a microscope that alters the phase relationships of the light passing through and that passing around the object, the contrast permitting visualization of the object without the necessity for staining or other special preparation.scanning electron microscope (SEM) an electron microscope that produces a high magnification image of the surface of a metal-coated specimen by scanning an electron beam and building an image from the electrons reflected at each point.simple microscope one that consists of a single lens.slit lamp microscope a corneal microscope with a special attachment that permits examination of the endothelium on the posterior surface of the cornea.stereoscopic microscope a binocular microscope modified to give a three-dimensional view of the specimen.transmission electron microscope (TEM) an electron microscope that produces highly magnified images of ultrathin tissue sections or other specimens. An electron beam passes through the metal-impregnated specimen and is focused by magnetic lenses into an image.x-ray microscope one in which x-rays are used instead of light, the image usually being reproduced on film.

x-ray mi·cro·scope

a microscope in which images are obtained by using x-rays as an energy source that are recorded on a very finely grained film; alternately, the image can be enlarged by projection; if film is used, it may be examined with a light microscope at fairly high magnifications.

x-ray mi·cro·scope

(rā mī'krŏ-skōp) A microscope in which images are obtained by using x-rays as an energy source that are recorded on a very fine-grained film, or the image is enlarged by projection; if film is used, it may be examined with the light microscope at fairly high magnifications.

释义	x-ray microscope x-ray microscope n. An instrument using x-rays to render a highly magnified image. x-ray microscope 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. x-ray microscope microscope [mi´kro-skōp] an instrument used to obtain an enlarged image of small objects and reveal details of structure not otherwise distinguishable.The light path of a darkfield microscope.
