Abstract: The laboratory wavelength calibration of the SWS has been successfully transferred to the in orbit situation. The achieved accuracies for the grating sections are lambda/delta lambda similar to 10000. Any remaining errors in the wavelength scale are dominated by uncertainties of the relative position of the target in the 14'' - 20'' wide slits. The grating spectral profile is very well represented by a Gaussian shape. The width of the grating spectral profile can be accurately predicted by a theoretical model. The wavelength calibration of the FP's is accurate to within 1/3 Of a resolution element, corresponding to lambda/delta lambda similar to 10(5). The wavelength stability of the gratings and FP is excellent, no measurable changes were found during the first 6 months of the ISO mission.
