Abstract
A spectrograph usable more particularly in the far ultraviolet range. It comprises along the Rowland circle measuring blocks including photo-detectors. Said measuring blocks are movably mounted along a guiding rail materializing the Rowland circle. Motion means are provided for the displacement of the various measuring blocks along the guiding rail. Transmission means between the motion means and a measuring block constantly direct the latter towards the diffraction grating.
