[[File:ISIM 3 logical region.jpg|thumb|upright=2|This is a diagram of an infrared space telescope that needs a cold mirror and instruments. One instrument needs to be even colder, and it has a cryocooler. The instrument is in region 1 and its cryocooler is in region 3 in a warmer region of the spacecraft (see [[MIRI (Mid-Infrared Instrument)]] or [[James Webb Space Telescope]]).]]
