Abstract. Liquid lenses, the geometric shape (radius of curvature) and, consequently, the optical power of which are regulated by changing the intra-lens fluid pressure, are developed. Results of experimental testing of electrically controlled liquid lenses on a hydraulic basis are demonstrated. The presented version of the design with an electromagnetic actuator serves as the basis of the lens for night vision glasses. The optical scheme and technical characteristics of the lens are given.
Keywords: liquid lens, optical system, objective, optical-electronic system, autofocus, night vision
