The optical properties of carbon spheroids are compared with those of carbon spheres for all size regimes. In general, the absorption cross section/unit volume is increased by axial elongation, particularly away from the resonance region. The results are specific to carbon since the effect of shape change in a given size regime can depend crucially on the value of the refractive index.
