English: A diagram of a Czerny-Turner monochromator.
Light (A) is focused onto an entrance slit (B) and is collimated by a curved mirror (C). The collimated beam is diffracted from a rotatable grating (D) and the dispersed beam re-focussed by a second mirror (E) at the exit slit (F). Each wavelength of light is focussed to a different position at the slit, and the wavelength which is transmitted through the slit (G) depends on the rotation angle of the grating.
Deutsch: Ein Diagramm eines Czerny-Turner-Monochromators.
Licht (A) wird auf den Eintrittsspalt fokussiert (B) und wird mit einem Konkavspiegel kollimiert (parallelisiert) (C). Der kollimierte Strahl wird durch ein drehbares Gitter gebeugt (D) und der dispergierte Strahl wieder durch einen zweiten Spiegel fokussiert (E) auf den Austrittsspalt (F). Jede Wellenlänge des Lichtes wird auf einer anderen Stelle des Spaltes fokussiert. Die Wellenlänge, die durch den Spalt (G) hindurchgelassen wird, hängt vom Drehwinkel des Gitters (D) ab.
