Paper Abstract

We present designs for compact near-IR spectrometers with mid to high resolving powers. They use an innovative combination of integral-field units and immersed gratings, both with and without cross-dispersion. The advent of ELTs with scientific requirements for multi-channel instruments (e.g. EAGLE) with high resolving powers has led to designs for spectrometers which are made more compact by using immersed gratings and are capable of high spectral resolving power by including cross dispersion and an arrangement of the IFU output that provides the requisite short slit.
