A grating spectrometer has been designed and built which allows extremely rapid scanning rates (over 200 Å/ µsec) over a wide spectral range (4000–11,000 Å) in one order with a theoretical resolving power of ~6000. The basic principles of the instrument are described together with some spectra (taken at speeds of ~90 Å/µsec) illustrating its capabilities.
