The Improved Stratospheric and Mesospheric Sounder (ISAMS) is designed to measure the Earths middle atmosphere in the range of 4.6 to 16.6 microns. This paper considers all the coated optical elements in two radiometric test channels. (Analysis of the spectral response will be presented as a separate paper at this symposium, see Sheppard et al).
Comparisons between the computed spectral performance and measurements from actual coatings will be discussed: These will include substrate absorption simulations.
The results of environmental testing (durability and stability) are included, together with details of coating deposition and monitoring conditions.
