Abstract

Low loss coherent bundles can be used in the area of broadband infrared and thermal imaging. We have been able to extend the present hollow glass waveguide (HGW) technology to very small bore sizes, from 250 down to 50 ?m. HGWs with bore sizes from 50 to 320 ?m have been used to make flexible bundles. These bundles are then coated with Ag/AgI thin films using liquid phase chemistry techniques. The optical properties of these bundles were studied by FTIR spectroscopy. These bundles have relatively low loss in the wavelength range of 8 to 12 ?m.
