Enhanced MODIS Airborne Simulator

SDL provided a cooled optical bench assembly (COB) to enhance the MODIS Airborne Simulator (MAS), a wide-band, multispectral, whiskbroom scanner operated by the NASA Airborne Sensor Facility for Earth-observing campaigns aboard high-altitude NASA platforms.

The COB contains instrumentation for 12 LWIR bands and one MWIR band, with accommodation for 12 MWIR bands. The MAS spectral bands span from 0.45 to 14.0 μm and are similar to those of the MODIS (Moderate Resolution Imaging Spectroradiometer) instrument aboard the AQUA and TERRA satellites.
