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).
A medium-sized dewar is being filled with liquid nitrogen by a larger cryogenic storage tank.
