摘要: Abstract Based on a composite preform concept, systematic investigation has been carried out in order to qualify low-refractive-index fluorophosphate glass that would be chemically and physically compatible with low-phonon-energy barium-indium-gallium-based fluoride glass. Special attention is paid the stability towrds devitrification of solid solutions may form at interface two glasses thermomechanical compatibility glasses. The most significant result exhibits theoretical refractive index difference, Δn, nearly 0.07.
