Protective antireflection coatings for optical IR fibers based on silver halogenides

The polycrystalline optical IR fibers based on silver halogenides AgCl-AgBr exhibiting low losses (0.5 dB/m and less) in the wavelength range from 4.0 to 16.0 micrometers are of interest in technical and medico-biological applications as fiber optic sensing devices and flexible systems for delivery of low-power CO2 and CO lasers radiation.
