Paper Abstract

Infrared gas monitoring instruments have mainly been constructed around various filter arrangements, some of which are suffering from spectral interferences due to large optical bandwidths and temperature sensitivity. It is the purpose of this paper to describe the use of concave, aberration corrected holographic gratings as wavelength selective elements in these applications in order to reduce interferences and gain higher wavelength stability. The wavelength range discussed is about 2-10 micron. An example of a novel two element gas monitor is presented.
