About The Spitzer telescope is a reflector of lightweight Witchery-Chretien. Weighs less than 50 kg and is designed to operate at an
extremely low temperature. The telescope has a hole of 85 cm in
diameter. All parties except the support of the mirror are made of
lightweight beryllium. Beryllium is a very strong material that works well in
the construction of space telescopes infrared, because has a specific heat low
to very low temperatures. The telescope is attached to the upper shell of
the Crystal cooled by steam, which maintains the science instruments too cold.
