title: Infrared optical filters for the infrared atmospheric sounding interferometer meteorological space instrument.
abstract: Optical coatings are designed and produced for the Infrared Atmospheric Sounding Interferometer meteorological space instrument operating in the spectral range 3.5 15.5 m. First we discuss the choice of substrates and determine the complex refractive indices of thin-film materials. Then several theoretical solutions are studied for optimizing the efficiency of the instrument. To allow us to study the feasibility of the coatings, a specific mid-infrared optical monitoring system has been developed. This system is validated by the successful manufacture of two-cavity Fabry Perot filters.
