G. Westermeierratings during the last decade. Both turn out to be realizations of long-held dreams. One is the accurate solution of Maxwell’s equations for diffraction gratings, so that diffraction efficiency can be theoretically predicted for any groove geometry, wavelength, material and angle of incidence.

é spectrograph of the 2.7-m telescope at McDonald Observatory under conditions typical of high-resolution astronomical spectroscopy. Spectra of a current-stabilized quartz-iodine incandescent lamp were obtained with both gratings in the wavelength range 5900–6800 Å using a Reticon array as detector.
