Abstract

Spectroscopic measurements were used to evaluate the effect of water adsorption and desorption on IR fibers transmission. Water impurities attenuated the transmission of silver halide IR fibers at 2.94 micrometers , 6.32 micrometers , and at wavelengths longer than 10 micrometers . Water is adsorbed from the humidity of the air, and the adsorption is a slow exponential process that reaches saturation in a few months. Most of the water can be desorbed by heating the fibers to 110 - 140 degree(s)C for a few hours in air or in vacuum.
