Effect of Stray Light in Prism and Grating Spectrographs on Emulsion Calibration Curves and Its Significance in Spectrographic Analysis

Abstract

Several investigators have observed that emulsion calibration curves obtained from spectrograms exposed in Littrow mounting prism spectrographs exhibit a smaller slope than the corresponding curves obtained from spectrograms exposed in Wadsworth mounting grating spectrographs. A study of the nature of this difference has shown that stray light originating from direct reflection and lens flare at the collimating-camera lens in the Littrow prism spectrograph is responsible. Since the magnitude of the integrated stray light radiation falling on any area of the emulsion is dependent on the number and proximity of exposures, the slope of the emulsion calibration curves obtained from Littrow spectrograph exposures may change with placement on the plate, unless focal-plane diaphragming is employed. The significance of this stray light factor in spectrographic analysis and in relative intensity measurements is discussed.
