Abstract: Analytical approximations for calculations of the luminous efficiency of Bragg crystal diffraction spectrometers with flat and focussing crystals are derived. The given approximative formulas are in good agreement with ray-tracing calculations presented in an earlier work. Influences of the geometric source dimensions on the luminous efficiency are discussed for both spectrometer types mentioned.
