Abstract

A combination of a plane grating and a spherically concave holographic grating is studied and optimized for imaging of distant objects in selected wavelength bands with a high degree of chromatic correction. The recording conditions for the holographic grating are given, and the aberrations of the image are studied. The arrangement comprises a new type of diffracting telescope. The achromatic imaging is verified by numerical ray-tracing and by experiment, the results of which are given.
