The high altitude (4500 meters), low temperatures and low precipitable water vapour content during most of the year make it a promising site for mid-infrared observations as well. We have designed various optical configurations for a mid-infrared imager with the twin goals of producing diffraction limited images and suppressing thermal backgrounds. After considering various challenges for implementation, we suggest the off-axis reflector design as the most suitable option. We present this design along with a brief listing of science cases. |
