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 ...
Because of the need for new universities and colleges during the post-war period, there was a demand for microscopes and accessories and Prior developed instruments for this market.
