Abstract

A tandem gratings spectrometer with high imaging quality is designed. By applying the geometric analysis, the spectral broadband anastigmatic imaging conditions have been obtained. It offers an advanced design with low aberrations for the whole spectral range of the small-scale spectrometer both in the off-axis and coaxial telescope applications. A UV design exhibiting excellent optical performance is presented. The specifications of design have also been investigated.
