Abstract
PURPOSE:To produce the titled lens having an arbitrary diameter by adding a dopant compd. for regulating refractive index to silica sol and by converting the sol into gel under centrifugal force. CONSTITUTION:A dopant compd. for regulating refractive index is added to silica sol obtd. by hydrolyzing alkyl silicate and adding fine silica powder. The silica sol contg. the dopant compd. is converted into gel under centrifugal force to form a prescribed concn. distribution of the dopant. The resulting gel is dried and sintered to obtain a transparent glass body. By this method, a distributed index lens having an arbitrary diameter can easily be produced.
