title: Image orthicon spectrograph with computer control.
abstract: A spectrograph using an image orthicon tube for low light level spectroscopy has been constructed. It has been tested for rapid raman spectroscopy and, with computer control, for transient absorption spectra of ions excited to metastable states. The advantages and disadvantages of the instrument are discussed.
