A variable mirror ( 100; 200; 300; 400; 500; 600; 740; 922 ) includes a fluid chamber ( 130; 230 ), an optical axis ( 90 ) extending through at least a portion of the fluid chamber, and a first polar and/or conductive fluid ( 110; 210 ) and a second fluid ( 120; 220 ) in contact over an interface ( 140, 140'; 240, 240'; 340, 340'; 440, 440'; 540, 540' ) extending transverse the optical axis. The fluids are substantially immiscible. The interface comprises a reflective material. An interface adjuster ( 250; 250'; 250'' ) is arranged to alter the configuration of the interface via the electro wetting effect. |
