Gradient Index Lenses From Sol-Gel Layering.
Abstract
This is the third and final annual technical report of an AASERT grant award covering the period from 1 July 1993 to 30 June 1996. The research proposed is based on the concept of the liquid gradient density column,1 which is used to measure the density of doped semiconductors. This technique uses a column made from two miscible liquids of different densities, configured to exhibit a continuous variation in density from the bottom to the top of the column. With the most dense liquid at the bottom and the lighter liquid at the top, the gradient is a function of the starting densities of the starting materials. Such gradient columns are stable up to several months and allow an accuracy in density measurement of up to five significant digits. It is assumed that density differences can be directly correlated with differences in refractive index. In this research the principle of the gradient density column is applied to the sol-gel process. The sol-gel process has been widely studied in the recent past, as it is an interesting alternative chemical route to conventional glass and ceramics processing.
