In this erratum, a correction of a previously computed extinction spectrum of a sample of silver fibers in the infrared [Appl. Opt. 48, 5095 (2009) [CrossRef] ] is reported. The spectrum was inaccurately computed through use of an approximation relating the E-field aligned values to those of the orientationally averaged extinction efficiency. This approximation is very close for spectral points in the vicinity of the primary resonance but not necessarily for those well away from this resonance. Here, the exact theory has been used to produce the spectra.
