Abstract

In this paper it will be seen that an aberration corrected holographic diffraction grating can function as the sole optical component in a spectrograph. The use of such a grating has shown that over a flat focal plane, resolution was maintained. In the examples described, two gratings were tested; one of which operated in the range of 2000-8000Å, the other 4000-8000Å, each range distributed over 25mm. Resolution was found to be constant up to lmm on each side of the optical axis perpendicular to dispersion, permitting spatial resolution with wavelength. The device is reviewed in terms of its applications in astronomy and analytical spectroscopy.
