Abstract

The GEMINI 8-meter Telescopes Project is designing twin 8-meter telescopes to be located in Hawaii and Chile. The GEMINI telescopes will have interchangeable secondary mirrors for use in visible and infrared. The APART/PADE program is being used to evaluate the effective infrared emissivity of the IR configuration plus enclosure as a function of mirror contamination at three infrared wavelengths. The goal is to design a telescope whose effective infrared emissivity is no more than 2% when the mirrors are clean.
