The performance of a large echelle grating in a solar spectrometer

Solar Physics, 1967
A number of tests of a large diffraction grating are described. It is shown that useful information about the performance of the grating in a spectrometer can be obtained from an analysis of the diffracted wavefront by the method of Stroke. Comparison of the instrumental profile at three wavelengths strongly suggests that the influence of changes in ...

Baranne Type Spectrograph with Echelle Grating

Optik, 1976
Many astrophysical problems can only be solved by using high dispersion spectrographs. Until recently, Coude-spectrographs have been the most commonly used type of spectrographs for this purpose. But with modern grating ruling techniques it is possible to rule larger echelle gratings and this brings up new possibilities for the spectrograph design.

A Comparison of Holographic and Echelle Gratings in Astronomical Spectrometry

1988
An efficiency comparison was made between a 2400 groove/mm holographically-ruled diffraction grating and the 7 9-groove/mm echelle grating in the coude spectrograph of the 2.7-m telescope at McDonald Observatory under conditions typical of high-resolution astronomical spectroscopy.
