PREPARATION OF A LIGHT FOCUSING GLASS ROD BY ION-EXCHANGE TECHNIQUES
A glass rod with a radially graduated refractive index was produced by replacing the lithium ions contained in the glass composition with sodium ions from a fused salt bath. Glass rods with such refractive index gradients are potentially useful as low resolution imaging devices.
