Paper Abstract

Amorphous Materials has developed a chalcogenide glass which can be drawn in unclad fibers continuously with diameters as low as 50 micrometers . The glass, designed C4, was used to form bundles using the stacked ribbon method. The bundles, 1 meter long and containing 4 - 5 thousand fibers, fitted with relay and objective lenses, produced images using the 3 - 5 micrometers Agema 210 camera far superior than observed at Amorphous Materials with previous bundles. Resolution and contrast were markedly improved. Further improvement was observed when a bundle was used with a much more sensitive Raytheon Radiance it 3 - 5 micrometers camera. FTIR scans showed the transmission was low in the 8 - 12 micrometers range. Images obtained using a Raytheon Palm IR were faint with low contrast. Antireflection coating on the bundles improved 3 - 5 micrometers transmission but failed to improve the 8 - 12 micrometers performance sufficiently.
