Assessment of the performance of a compact concentric spectrometer system for Atmospheric Differential Optical Absorption Spectroscopy
Assessment performance compact concentric spectrometer system Absorption Spectroscopy
2010/2/8
A breadboard demonstrator of a novel UV/VIS grating spectrometer has been developed based upon a concentric arrangement of a spherical meniscus lens, concave spherical mirror and curved diffraction gr...
Broadband Cavity Enhanced Differential Optical Absorption Spectroscopy (CE-DOAS) – applicability and corrections
Broadband Cavity Absorption Spectroscopy applicability corrections
2010/2/8
Atmospheric trace gas measurements by cavity assisted long-path absorption spectroscopy are an emerging technology. An interesting approach is the combination of CEAS with broadband light sources, the...
A cavity ring down/cavity enhanced absorption device for measurement of ambient NO3 and N2O5
cavity ring down cavity enhanced absorption device ambient NO3 N2O5
2010/2/8
An inexpensive, compact instrument for the sensitive measurement of NO3 and N2O5 in ambient air at high time resolution is described. Light from a red-emitting laser diode (≈662 nm) is coupled off-axi...
