摘要:
This invention relates to a method of performing an ion exchange of optical glass to produce an axial gradient index material having a good linear distributiion by bringing a glass body containing a monovalent cation component into contact with a medium containing a monovalent cation component and exchanging these cation components under a predetermined condition.
