A hyperspectral imaging spectrometer was breadboarded. Key innovations were use of a sapphire prism and single InSb focal plane to cover the entire spectral range, and a novel slit optic and relay optics to reduce thermal background. Operation over a spectral range of 450 - 4950 nm (approximately 3. 5 spectral octaves) was demonstrated. Thermal background reduction by a factor of 8 - 10 was also demonstrated.
