Designing compact S-shaped optical layouts of spectrographs

摘要

This paper describes a technique for designing a compact spectrograph whose optical layout includes a holographic diffraction grating for correcting aberrations and a concave projection mirror. The image quality is modeled and evaluated for a specific layout. Spectrographs are presented that are constructed using an analogous layout but have increased speed or improved spatial resolution.
