The development of the fiber optics technology for a lanthanate-soda lime glass combination and for an arsenic sulphur glass combination is reported. The former glasses can be used over the wavelength range of 0.4 to 5 microns and the fiber drawing processes are those normally used for high softening point glasses available in a rod and tube form. The fabrication of fused plates, field flatteners, light pipes, image dissectors and high resolution imaging cones is reported. The arsenic sulphur glasses, for use over the 1 to 12 micron range, are not available in a rod and tube form so a concentric crucible technique was developed for the production of single coated fibers. This process and the processes used for drawing multiple fibers and fabricating components are fully described. These components include high resolution fused plates, field flatteners, light pipes, image dissectors and low resolution imaging cones. A full description is also given of the processes developed to evaluate these fiber optics components at infrared wavelengths and data are presented on the spectral transmission, edge response and detailed optical transfer functions of each component.
