The edge radiation emitted from a bending magnet edge in an electron storage ring is considered for wavelengths sufficiently long that the spatial extent of the magnet edge may be neglected. For a typical electron storage ring with energy {>=}800 MeV, this 'zero edge length' model applies to the infrared region. The far-field edge radiation is radially polarized, directed in a cylindrically-symmetric hollow cone along the straight-section axis with peak intensity at an opening angle of 1/{gamma}, where {gamma} is the relativistic mass factor. At the wavelength, {lambda}, the near field occurs at observer distance, R, less than {lambda}{gamma}{sup 2}. The near-field edge radiation is also radially polarized, forming a hollow cylindrical distribution with peak intensity at a distance (R{lambda}){sup 1/2} from the straight-section axis.
