Abstract:
A clad glass composition that is excellent in devitrification resistance and that prevents the whole mother glass rod from devitrifying by preventing a core glass composition from devitrifying in forming a mother glass rod using a concentric crucible drawing method, is provided. The clad glass composition forms a clad of a mother glass rod for a gradient-index rod lens having a core/clad structure.
