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.
The telescope's design philosophy is based on the following
points:
Maximize the use of materials with a ratio of hardness /
very high density, high thermal conductivity, specific heat and cryogenic low.
Build the entire telescope of the same material to prevent
complications from thermal expansion, and make the telescope assembly as
dimensionally stable as possible.
Select a configuration that minimizes the size of the major
elements of the telescope assembly.
Exhaustively try the simplest design possible to minimize
the number of parts, thereby reducing the time and cost of design, manufacture
and integration.
