Spectrometers

Spectrometers provide the capability to remotely identify the composition and concentrations of atmospheric gas species and temperature. SDL has the experience and the optical design, detector application, precision fabrication, cryogenics, data processing, servo control, and vibration cancellation capabilities to design, analyze, align, and test spectrometers. SDL has over 50 years of heritage building spectral, spatial spectrometers for space and terrestrial applications.

Experience

GIFTS

Geosynchronous Imaging Fourier Transform Spectrometer

GIFTS was successfully tested and calibrated as an engineering demonstration unit to ground-validate technologies critical to NOAA’s Hyperspectral Environmental Suite for the Geostationary Operational Environmental Satellite (GOES) system.

CIRRIS-1A

Cryogenic Infrared Radiance Instrumentation for Shuttle

CIRRIS-1A’s goal was to obtain simultaneous spectral and spatial measurements of atmospheric emissions, including airglow and auroral phenomenology.

SPIRIT III

Spatial Infrared Imaging Telescope

SPIRIT III was the infrared sensor aboard MDA’s Midcourse Space Experiment (MSX). This long-wave infrared instrumentation package consisted of a high spatial resolution radiometer, a high spectral resolution interferometer-spectrometer, and an extremely high-off-axis-rejection telescope.

ICON-FUV

Ionospheric Connection Explorer-Far Ultraviolet Imaging Spectograph

The FUV instrument on the ICON mission is designed to measure daytime thermospheric and nighttime ionospheric density profiles.
