摘要： An optical apparatus includes: a sealing case having chambers partitioned by a partition wall; a polar liquid having polarity and a nonpolar liquid having no polarity which are respectively sealed in a predetermined amount in each of the chambers; and electrodes pulling the polar liquid by an electrowetting phenomenon upon application of a driving voltage. One of the polar liquid and the nonpolar liquid is colored with a color having a light-blocking property, and the other has a light-transmitting property, at least a part of the partition wall is positioned in an optically effective area including the optical axis, and when a driving voltage is applied to a predetermined electrode among the electrodes, the polar liquid is moved in the chamber between closed and open positions where the optically effective area is closed and open, respectively.

摘要： An optical element includes a container including first and second end face walls, a side face wall, and an accommodating chamber inside the walls; first and second liquids enclosed in the chamber; a first electrode provided on a surface of the first end face wall; a second electrode provided on a surface of the second end face wall; an insulating film provided on a surface of the second electrode; and a unit configured to apply a voltage. The shape of an interface between the liquids is changed by a voltage application, and a light transmission path, the center of which is a virtual axis passing through the end face walls in the thickness direction of the container, is formed in a portion of the second liquid. An opening having a diameter the same as or larger than the maximum diameter of the transmission path is provided in the first electrode.
