Abstract

An optical system with an electronically variable iris. The optical system comprises an optical lens. A number of transparent conductive layers is coupled to an optical surface of the optical lens. A liquid crystal film is separated into a number of portions by the number of transparent conductive layers, wherein a transmissive state of each portion, from the number of portions of the liquid crystal film, with respect to light is configured to change in response to application of a voltage to the number of transparent conductive layers.
