The diffractive lens consists of two cascaded variable liquid crystal‐based spiral diffractive lenses. Changing concertedly the topological charge changes the focal length with no mechanical motion. The implemented lens has a focal range from –2 to +2 diopters, an active diameter of 25 mm, a low operating voltage ( |
