The final preflight calibration tests of the CVFCircular Variable Filter II spectroradiometer were performed in the Aerospace Research Chamber 7V. These tests included linearity, absolute responsivity, angular response, frequency response, and wavelength calibration. The instrument was linear over most of its range, but displayed nonlinearity for high irradiance levels. Wavelength calibration was found to have not changed significantly from a previous calibration.
