Abstract

A novel ir measurement facility that generates a 43-cm diam collimated beam of radiant flux in a simulated exoatmospheric environment has been built and evaluated. The broadband and spectral irradiance of the beam was measured with a calibrated integral three-grating spectroradiometer. The irradiance values cover a range of 10⁸, with near Planckian distribution at higher flux densities. The beam source can also generate monochromatic radiation tunable from 2 μm to 32 μm. Diffraction losses at the source aperture have been estimated.
