Reflective spatial heterodyne spectrometers (SHS) are a class of interferometric sensor with the capability to provide high étendue/resolving power measurements of diffuse emission sources in the solar system. SHS instruments are compact and do not rely on large telescope apertures to achieve sensitivity, which makes them an attractive option for space flight experiments. The major limitation of the basic SHS design has been the narrow bandpass it samples for a given tune, which restricts the SHS to applications focused on the study of single emission line features. We report here on progress toward the development of a SHS instrument that can be remotely realigned across a wide bandpass, thus making the technique an effective complement or viable alternative to low resolving power spectrographs typically used on remote space probes. In the `tunable’ SHS (TSHS), the narrow sampled wavelength range of a single tune is slewed to specific target emission features through the precision rotation of internal mirrors. A prototype TSHS with a bandpass covering the range from 300-700nm has been tested for performance and stability in field observations at the McMath-Pierce Solar Telescope. The results of these observations will be presented. (This research funded by NASA grant NNG04GB36G)
