Heavily boron-doped, diamond films can become superconducting with critical temperatures Tc well above 4 K. Here we first measure the reflectivity of such a film down to 5cm-1, by also using coherent synchrotron radiation. We thus determine the optical gap 2Δ, the field penetration depth λ, the range of action of the Ferrell-Glover-Tinkham sum rule, and the electron-phonon spectral function α2F(ω). We conclude that diamond behaves as a dirty BCS superconductor.
