Patent Number Title Of Patent Date Issued
5173930 X-ray monochromator December 22, 1992
An x-ray monochromator, wherein a housing supports a plurality of mirrors forming a plurality of opposed mirror faces in parallel with each other and having thereon multilayer coatings, with each of said pairs of mirror faces being provided with identical coatings which are different fro
5146482 Multispectral variable magnification glancing incidence x-ray telescope September 8, 1992
A multispectral variable magnification glancing incidence x-ray telescope capable of broadband, high resolution imaging of solar and stellar x-ray and extreme ultraviolet radiation sources includes a primary optical system which focuses the incoming radiation to a primary focus. Two or
5107526 Water window imaging x-ray microscope April 21, 1992
A high resolution x-ray microscope for imaging microscopic structures within biological specimens has an optical system including a highly polished primary and secondary mirror coated with identical multilayer coatings, the mirrors acting at normal incidence. The coatings have a high
5016265 Variable magnification variable dispersion glancing incidence imaging x-ray spectroscopic telesc May 14, 1991
A variable magnification variable dispersion glancing incidence x-ray spectroscopic telescope capable of multiple high spatial revolution imaging at precise spectral lines of solar and stellar x-ray and extreme ultraviolet radiation sources includes a pirmary optical system which foc
4941163 Multispectral glancing incidence X-ray telescope July 10, 1990
A multispectral glancing incidence X-ray telescope is illustrated capable of broadband, high-resolution imaging of solar and stellar X-ray and extreme ultraviolet radiation sources which includes a primary optical system preferably of the Wolter I type having a primary mirror system (20,
4562583 Spectral slicing X-ray telescope with variable magnification December 31, 1985
A telescope (A) for viewing high frequency radiation. This telescope has a long focal length with a selection of magnifications despite a short housing (20). Light enters the telescope and is reflected by the telescope's primary optical system (10) and (12) to one of several secondar
4498749 Folded optical large format photomicrographic camera system February 12, 1985
A photomicrographic camera system is provided in which a mirror (26) is utilized to deflect the light beam emanating from the eyepiece (20) of a properly illuminated, compound optical microscope (10) horizontally outward to another mirror (30) which then deflects the beam vertically
4370750 Extended range X-ray telescope January 25, 1983
An X-ray telescope system comprises a tubular mount having a collecting region at one axial end for receiving X-rays from a remote source, and a detector region remote from the one axial end. A soft X-ray/XUV subsystem associated with the collecting region directs only relatively soft, n
4287152 Method of for retarding dye fading during archival storage of developed color photographic film September 1, 1981
Dye fading during archival storage of developed color photographic film (17) is retarded by placing the film in a sealed, opaque vault (10), introducing a dry, pressurized inert gas into the vault while the latter is vented, and sealing the vault after the air within the vault has been
