Space-View Simulators

Infrared sensors typically add a background which must be removed for accurate measurements of external scenes. During flight, the background is usually measured looking off into cold, dark, space. During ground testing, SDL’s space-view simulators provide a target to measure the sensor background.

Features

  • Cold and dark background similar to space
  • LN2 and LHe background temperatures
  • Cavity for high emissivity

FIRST

Far-Infrared Spectroscopy of the Troposphere

FIRST is a long–wave imaging spectrometer that measures between 10–100 µm, filling a gap in the existing systems that monitored the Earth’s climate.
