The Portable Remote Imaging SpectroMeter (PRISM) operates between the spectral range of 350 nm and 1050 nm, and offers high temporal resolution and below cloud flight altitudes to resolve spatial features as small as 30 cm. The sensor performance exceeds the state of the art in light throughput, spectral and spatial uniformity, and polarization insensitivity by factors of 2-10, while at the same time extending the spectral range into the ultraviolet.

PRISM has a two-channel spot radiometer at short-wave infrared (SWIR) band (1240 nm and 1640 nm). It is in co-alignment with the spectrometer in order to provide accurate atmospheric correction of the ocean color measurements.

The development of the PRISM instrument was supported by NASA Earth Science Division’s the Ocean Biology and Biogeochemistry, Earth Science Technology, and Airborne Sciences programs within NASA’s Earth Science Division. It is compatible with a wide range of piloted and Uninhabited Aerial Vehicle (UAV) platforms
