X-ray telescope which displays the X-ray radiation with wavelength (») is formed by a parabolic strip assembled from bent monocrystalline plates (1,2) with atomic planes (5) parallel with the surface of these monocrystalline plates (1,2), where their mutual distance in each monocrystalline plate (1,2) varies according to the equation
where n is a natural number, which determines the number of wavelengths (») belonging to the difference of the ray travel distances when reflecting from two neighbouring atomic planes (5), and p is double the distance of the focal line (F) from the vertex line (V) of the parabolic strip,
i.e. for given monocrystalline plate (1,2) laid between ( x min ) and ( x max ) the following equation applies
where ( d 0 ) is the distance between the neighboring atomic planes (5) at the point with coordinate ( x min ) and ( d ) is the distance between the atomic planes (5) at the point with coordinate ( x ). Such course can be achieved by distribution of temperatures in different places according to experimentally measured dependence of the grid parameter y on the temperature |
