Adjustable electro-optic microlens with two concentric ring electrodes.
A theoretical model of a new variable-focal-length lens design that uses an electro-optic wafer with two double-sided concentric ring electrodes is proposed on the basis of an original technique for calculating the induced refractive index. It is shown that the relationship between ring radii and wafer thickness produces the required distribution of the refractive index to create converging focusing elements.
