Collecting area of the main array as a function of the wavelength and angle in the field. The plateau corresponds to the full aperture (unvignetted), the side-lobes correspond to the decrease in beam section due to vignetting by the edges of the field optics when an off-limit wavelength or field angle is reached
The field optics in the secondary spacecraft cause vignetting at
wider bands, limiting to Δ λ / λ ≃ 20% in the
above example (Fig. 3 ). .
