| Zusammenfassung: | A shield designed for use in a spectrograph to prevent pre‐exposure and subsequent exposure of the photographic plate due to scattered light when a number of spectra are photographed on the same plate or film. The use of such a shield eliminates consequent errors in the densities of spectral lines as determined by a densitometer. |
