We present a FT-IR coupled goniometer setup, which allows the simultaneous spatial and spectral characterization of optical components used in non-dispersive infrared gas sensor systems. The per-formance of the laboratory setup is demonstrated by comparing reflector and Fresnel lens equipped thermal infrared radiation sources. We show that even the simplest binary Fresnel lenses, when opti-mally designed, can achieve a thinner emission angle than parabolic mirrors at comparable radiation intensities.
