In 1918, Einstein pointed out that the refractive index for X-rays in most mediums should be just slightly greater than 1, [3] which means that refractive optical parts would be difficult to use for X-ray applications. Early X-ray microscopes by Paul Kirkpatrick and Albert Baez used grazing-incidence reflective X-ray optics to focus the X-rays ...
Early X-ray microscopes by Paul Kirkpatrick and Albert Baez used grazing incidence reflective optics to focus the X-rays, which grazed X-rays off parabolic curved mirrors at a very high angle of incidence. An alternative method of focusing X-rays is to use a tiny fresnel zone plate of concentric gold or nickel rings on a silicon dioxide substrate
Antonie van Leeuwenhoek (1632–1723). The field of microscopy (optical microscopy) dates back to at least the 17th-century.Earlier microscopes, single lens magnifying glasses with limited magnification, date at least as far back as the wide spread use of lenses in eyeglasses in the 13th century [2] but more advanced compound microscopes first appeared in Europe around 1620 [3] [4] The ...
Sterling Price Newberry (August 10, 1915 – January 28, 2017) was an American inventor and microscopist.He was born in Springfield, Missouri.Newberry invented the shadow X-ray microscope and was one of the founders of the Microscopy Society of America.
X-ray optics is the branch of optics dealing with X-rays, rather than visible light.It deals with focusing and other ways of manipulating the X-ray beams for research techniques such as X-ray diffraction, X-ray crystallography, X-ray fluorescence, small-angle X-ray scattering, X-ray microscopy, X-ray phase-contrast imaging, and X-ray astronomy.
"showed Protective X-ray Gloves of a useful type, made of opaque flexible material, and very convenient for practical use; also an X-ray tube with a special arrangement of electrodes for improving the quality of the X-rays when operated with a coil by diverting the inverse impulses of the field of action.
1967: Erwin Wilhelm Müller adds time-of-flight spectroscopy to the field ion microscope, making the first atom probe and allowing the chemical identification of each individual atom. 1981: Gerd Binnig and Heinrich Rohrer develop the scanning tunneling microscope (STM). 1986: Gerd Binnig, Quate, and Gerber invent the atomic force microscope (AFM).
It is named after Paul Kirkpatrick and Albert Baez, the inventors of the X-ray microscope. [1] Although X-rays can be focused by compound refractive lenses, these also reduce the intensity of the beam and are therefore undesirable. KB mirrors, on the other hand, can focus beams to small spot sizes with minimal loss of intensity.
