Recent Developments in High Resolution Spectroscopy Using the IFS 120 HR

Abstract

In order to successfully produce high resolution spectra, a spectrometer must possess qualities such as precision optics, a high degree of optical stability, and sensitivity. Additionally, it is highly desirable that the instrument be versatile with respect to permitting a variety of samples to be scanned in the desired spectral regions. Otter practical considerations such as the time required to obtain the spectrum, and general ease of use should be considered in the spectrometer design. In order to meet such demanding criteria, it is clear that Fourier transform (FT) techniques would be appropriate.
