Tests are described of an arrangement for the direct photoelectric recording of stellar spectra, using a Fabry-Perot etalon in combination with a prism monochromator. The addition of the etalon allows the monochromator to be used with a wider entrance slit for given wavelength resolution : this results not only in a gain of light, but also in a reduction of the fluctuations caused by the motion of the stellar image under the influence of atmospheric turbulence.Description de tests effectués sur un dispositif d'enregistrement photoélectrique direct de spectres stellaires, utilisant la combinaison d'un étalon Fabry-Perot et d'un monochromateur à prisme.
