Schematic layout for the AEOS and HiVIS optical pathway when in the charge-shuffling configuration. The telescope optics are shown in blue. There are 5 flat fold mirrors that bring the beam in to the coudé room. The elevation and azimuth axes are labeled to show the optical changes during telescope tracking. The HiVIS optical relay which feeds both visible and infrared spectrographs and accomplishes tip/tilt correction is shown in green. The spectrograph optics are shown in red. All optical surfaces are shown. Polarization and calibration components are shown in black. The HiVIS modulator and analyzer are behind the spectrograph slit. All optics in blue and green contribute to telescope polarization cross-talk. The full-Stokes injection unit in front of the HiVIS spectrograph slit is for polarization calibration of the modulators and spectrograph. Additional calibration optics shown in black between the AEOS telescope (blue) and relay optics (green) are mounted at the entrance of the coudé room. These provide flat fielding, wavelength and polarization calibration light sources. See text for details.
