The required concentration-dependent diffusion coefficients for both ideal one-dimensional
and ideal radial gradient-index profiles are determined. The modified quasi-chemical …

Chromatic effects of radial gradient-index materials have been analyzed, and several
important conclusions have been derived in terms of material dispersion data. The use of …

We demonstrate use of the gradient-index (GRIN) spectral model to design an achromatic
low-power GRIN microscope objective. This new GRIN microscope objective, using simpler …

Manufacturing problems concerning glasses used for making of GRIN type lenses have
been presented. The most important requirements to glass quality is its high chemical and …
