Performance and selected applications of an acousto-optic tunable filter near-infrared spectrometer.
The design and applications of a near-IR (near-IR) spectrometer with an acousto-optic tunable filter (AOTF) as monochromator and light fiber optics are described. The aim of this spectrometer is rapid product and reaction control via remote sensing and chemometric data evaluation. Its application and performance are illustrated by the detn. of the H2O content of acetone and by the contact-free temp. measurement of an aq. soln.
