Paper Abstract

A mid-infrared imager and spectrometer is under consideration for construction in the first decade of the Thirty- Meter Telescope (TMT) operation (see the companion paper by Okamoto). MIRES, a mid-infrared high-spectral resolution optimized instrument, was previously proposed to provide these capabilities to the TMT community. We have revised the design in order to provide an improved optical design for the high-spectral resolution mode with R=120,000, improved imaging with sky chopping, low-spectral resolution mode with an integral field spectrograph, and polarimetry. In this paper we describe the optical design concepts currently under consideration.
