Diffuse Infrared Background Experiment (DIRBE) was an experiment on NASA's COBE mission, to survey the diffuse infrared sky. Measurements were made with a reflecting telescope with 19 cm diameter aperture. The goal was to obtain brightness maps of the universe at ten frequency bands ranging from the near to far infrared (1.25 to 240 micrometer). Also, linear polarization was measured at 1.25, 2.2, and 3.5 micrometers. During the mission, the instrument could sample half the celestial sphere each day.
