Abstract

Planar gratings for applications in infrared spectrometers have been prepared with curved, non-equidistant groves by lithography and a deep etching process. The gratings feature focusing properties as well as the ability to tailor the spectral dispersion dependency, allowing a compact dispersive IR spectrometer. We report on the design, fabrication and characterization measurements. Based on these results, a concept for a compact spectrometer prototype utilizing thermoelectric detector arrays with high detectivity was developed.
