Influence of edge effects on performance of electrooptical lens

The influence of edge effects on electrooptical lens performance is quantitatively assessed by solving the problem of the potential distribution in a crystal with semiinfinite electrodes. Significant distortions are detected along the x axis, which are plotted as a function of the instance from the center of the lens, demonstrating good agreement between the theoretical and experimental data. The nature and amount of distortions are found as a function of the degree of limiting of the electrodes.
