Abstract
The object of the prevent invention is to provide an optical system for producing variable refraction with minimized dispersion. A first material with a first apex angle in a first state and a second material with a second apex angle in a first state produce a first net refraction angle in at least two frequencies of electromagnetic radiation such that the beams that entered parallel exit parallel (to within a controllable tolerance). Said first material with said first apex angle in a second state and said second material with said second apex angle in a second state produce a second net refraction angle in at least two frequencies of electromagnetic radiation such that the beams that entered parallel exit parallel (to within a controllable tolerance).
