We are developing a high-resolution cross-dispersed echelle spectrograph for installation at one of the coude foci of the new AEOS 3.67 meter telescope, operated by the Air Force Space Command on Haleakala, Maui, Hawaii. The spectrograph will consist of two major subsystems: an optical arm for the wavelength range 0.5-1.0 micrometers and an IR arm for the range 1.0-2.5 micrometers . Both arms of the spectrograph use a white- pupil collimator design to maximize grating efficiency and to limit the size of the camera optics. The optical arm of the spectrograph will use deep-depletion CCDs optimized for operation near 1.0 micrometers . The IR detector will be a 2048 by 2048 HgCdTe array that has bene developed by the Rockwell Science Center for this project. Both the optical and IR arms of the spectrograph will be equipped with slit-viewing cameras for object acquisition and control of a fast guiding tip-tilt mirror located in a pupil image in the spectrograph fore optics.
