Abstract

In previous papers, we reviewed the development of multilayer optics, the successful application of this new technology to astronomical observations, the evolution of astronomical multilayer optics instrumentation through several generations, and the matching of multilayer bandpasses to the coronal spectrum. These developments have resulted in the acquisition of sub-arc-second images of the sun in several wavelength bands, permitting solar structures to be simultaneously observed over temperatures prevailing in the chromosphere (approximately 10,000 K - 100,000 K), the transition region (approximately 100,000 K - 1,000,000 K) and the corona (> 1,000,000 K). In the present paper, we discuss the selection of spectral bandpasses that permit a set of isothermal coronal and chromospheric images of diagnostic quality to be formed.
