What X-ray beam characteristics can an AXCO optic produce?
Our optics can achieve many different beam geometries for a range of X-ray sources. The analogous conventional optical systems are lenses and cylindrically-symmetric mirrors. Using a pointlike or extended source, a beam can be produced that is either focused at some distance from the optic (1mm to 1m), parallel or divergent. Beam spot sizes at a specimen position from a few microns to several mm can be specified. In addition, nonuniform beam intensity profiles at the specimen may be advantageous where the spot size may be user-selectable by means of interchangeable apertures or collimators, to enhance relative performance from smaller beam sizes. Spectral characteristics are also designed into the optic – for bombardment sources, typically the primary spectral line energy is optimally reflected and higher energies suppressed. For synchrotron or continuum applications, an optical design is optimised for the energy band desired by the customer. Do I need a custom designed optic? Our expe
