Ewald sphere. ▫ Area detectors: – Image contains curved 2D slice in 3D space. – Each pixel has Because the radius of the Ewald's sphere (1/l) of the electron beam is large in comparison to the reciprocal lattice, (along with beam convergence and small Forskningsfinansiär. Stiftelsen för strategisk forskning (SSF), AM13-0049. Anmärkning. QC 20200929.

A most useful means to understand the occurrence of diffraction spots is the Ewald construction. Let's begin slowly: We draw a sphere of radius 1/lambda, in the center of which we imagine the real crystal. The origin of the reciprocal lattice (RL, see above) lies in the transmitted beam, at the edge of the Ewald sphere. Ewald’s sphere was named after a German physicist and crystallographer, Paul Peter Ewald because of his relevant publications. He first applied this geometric construction in X-ray crystallography which illustrates the relationship between: Ewald's sphere Last updated April 16, 2020.

Goto Contents: This example shall illustrate the different 'scans' in reciprocal space and allows you to see the path a THETA-scan and a H-scan follows. Curvature of the Ewald sphere limits the resolution at which Fourier components in an image can be approximated as corresponding to a projection of the object.

Ewald's sphere can be used to find the maximum resolution available for a given x-ray wavelength and the unit cell dimensions. It is often simplified to the two-dimensional "Ewald's circle" model or may be referred to as the Ewald sphere.
