Paper Abstract

A model is presented for the spectral degradation introduced into Fourier transform spectroscopy by imperfect optical figure. It allows tolerances to be defined for the figure of the optics if a required level of performance is to be achieved. It confirms the validity of the practical rule-of-thumb that optical figures true to within a tenth of the shortest wavelength of interest will not degrade performance unacceptably.
