SciGlob proposesnbsp;the development of an optimized miniature spectrometer for improved trace gas monitoring and satellite validation.
The new spectrometer will be substantially superior to the ones currently used giving higher signal-to-noise ratio, having less stray light and better temperature stabilization, and also a more repeatable manufacturing and alignment process. Thisnbsp;will significantly improve thenbsp;accuracy for ground-based remote sensing trace gas retrievals.
Out of several designnbsp;improvements, we consider the following items as the main innovative aspects of the proposed system:A round-to-slit fiber concept is applied to increase the system throughput.Application of a resistant black paint to the inner walls of the bench to reduce stray light.The TEC is integrated into the spectrometer and a micro-dehumidifier is added.The optical bench is 3D-printed.3D surface metrology is used to optimize the spectrometer alignment.
