Steward Observatory is building a deformable f/15 secondary mirror that will compensate for atmospheric turbulence for the 6.5m Multiple Mirror Telescope conversion. With the proposed adaptive optics system, this new telescope is expected to resolve diffraction limited images, approximately an order of magnitude better than present seeing. This improved visibility with a larger light collecting area and low thermal background requires a new science instrument, diffraction limited for the 1 to 5 micrometers region. This science instrument, presently in its early manufacturing stages, consists of four cameras, low resolution spectroscopy with grisms, high resolution spectroscopy with a cross-dispersed Echelle grating and an atmospheric dispersion corrector. The cameras will provide simultaneous slit viewing, differential imaging and two pixel sampling over the full wavelength band. Each camera will operate with a 1024 X 1024 HgCdTe array optimized for the spectral region of the camera. An IR tip/tilt sensor is also incorporated into the instrument that will relay natural guide star motion to the adaptive secondary in a closed-loop approach. This paper is an optical design instrument overview.
