Abstract

The use of spectrographs with telescopes having high order adaptive optics systems offers the possibility of achieving near diffraction-limited spectral resolving power. The adaptively corrected echelle spectrograph (ACES) couples the AO-corrected stellar image to the instrument with a near single mode fiber (SMF) for resolution of R~190,000. The First Light Adaptive Optics system (FLAO) at the Large Binocular Telescope (LBT) achieves Strehl of >80% in H band, and also delivers useful Strehls in V and R bands. In this paper we explore the possibility of using ACES with the LBT for simultaneous high resolution, high throughput, and broad wavelength coverage.
