Abstract
Santa Barbara Infrared, Inc (SBIR) has developed a dual-band infrared spectroradiometer for highly accurate radiometric calibration of electro-optical (EO) test stations, light sources, and optical surfaces. The "RAD-9000" design covers the 3-5 mm and 8-12 mm spectral bands, provides thermal sensitivity of better than 40 mK, supports object temperatures from 278-373 K, and delivers better than 2% spectral resolution (Dl/l). The RAD-9000 features computer-controlled operation, an intuitive graphical user interface (GUI), motorized focus adjustment, VIS-CCD sighting/alignment capability, less than 2 mrad detector IFOV, and an internal ambient reference for background subtraction and enhanced stability. In addition to high-performance relative radiometry, the RAD-9000 offers a high degree of absolute radiometric accuracy by utilizing a dedicated radiometric reference module. The reference module incorporates two 8-inch, variable temperature, high-emissivity extended sources to provide a stable, accurate absolute radiometric reference external to the main optics.
