Abstract: A arrangement uses a series of secondary slits which are mounted on a Rowland circle with a concave system and the primary slit. Luminous detectors in the form of photomultipliers are located behind the secondary slits. A mark allows only light to enter a photomultiplier from a narrow slit facing a secondary slit. The photo multiplier has a photocathode which is aligned with the concave system. As the primary slit is moved, the spectral displacement occurs. This movement is controlled from a calculator which also controls the position of the photomultiplier, the photo multiplier is mounted on a cam in order that its axis remains aligned with the centre of the concave system.
