Water Detection

H20 absorption spectra
Water has very strong absorption band at 2550-2750 nm and 1830-1900 nm. When applying IBSG LEDs and PDs it is more preferable to use the second absorption band at 1830-1900 nm since emitters and detectors for this spectral range provide much better efficiency (the data are taken from HITRAN Catalog).
H20 - second absorption band
H20 - main absorption band
