Deep thermal infrared capability for the Multiple Mirror Telescope: demands of multimirror telescope technology on infrared instrumentation

L. D. Keller, B. A. Sabol, G. H. Rieke

Abstract

This paper describes the Multiple Mirror Telescope (MMT) facility and discusses the demands placed upon the MMT by observations with the Thermal Infrared Photometer system, with special attention given to the subsequent modifications of the MMT-Photometer facility. It is shown that the MMT-Photometer competes well in sensitivity with similar detector systems currently operating on conventional single-mirror telescopes. The instrument will reach N (10.6 microns) magnitudes of 10 or better in integrations of one hour through a 5.4 arcsec aperture.
