Abstract
This paper presents the analysis of the geometrical components in the evaluation of the spectral resolution of X-ray bent crystal spectrometers. A toroidal Johann–Johansson type spectrometer is suggested and its resolution is estimated. Emphasis is made on the study of asymmetrically cut schemes. Generally used expansion techniques up to second order are added by calculations of the third term where second order becomes zero.
