Abstract

In gradient-index glass the variation of glass composition can also cause a variation in the thermal properties across the gradient region. The difference in thermal expansion and dn/dT across the gradient-index region has been modeled. Several examples illustrate how the models can be utilized to select gradient-index glass compositions that will have constant thermal properties within the gradient region. Experimental measurement of the variations of αL and dn/dT in gradient-index glass is presented in a separate paper.

Through personal communications with Baak it was confirmed that the values for ki and γi reported in Table IV of his paper are in error by a constant multiplicative term, n/(n − 1). Table VII (this paper) shows that good agreement between the model and catalog data is obtained when the recalculated values for ki and γi from Table VI of this paper are used. [CrossRef]
