Preparation of radial GRIN material with low distributed dispersion by a sol-gel process

Hiroaki Kinoshita; Morinao Fukuoka; Yuko Morita; Hisashi Koike; Satoshi Noda

A radial gradient-index (r-GRIN) material with low distributed dispersion (T10 equals 0.003, V10 equals 340) was successfully prepared by sol-gel process in SiO2-TiO2BaO-K2O system. The r-GRIN lens with flat surfaces performed little chromatic aberration. Sol-gel synthesis process using metal salts to realize the r-GRIN materials with low distributed dispersion was investigated. The low distributed dispersion was achieved by convex distribution for barium and even distribution for titanium against silicon along a diameter. The sol-gel process enables to prepare r- GRIN materials which have necessary low distributed dispersion on demand.
