Abstract
The present invention relates to a method of manufacturing an electrowetting-based variable-focus lens, comprising: (a) providing an enclosure having a cavity (17) and at least one channel (27, 28; 59) communicating at one end with the cavity and at the other end emerging at the exterior surface of the lens; (b) filling the cavity with first and second liquids (44, 47) that are immiscible and of different refractive indices via the channel; and (c) hermetically scaling the channel.

Method of manufacturing an electrowetting-based variable-focus lens, comprising:
- (a) providing an enclosure having a cavity (17) and at least one channel (27, 28;
- 59) communicating at one end with the cavity and at the other end emerging at the exterior surface of the lens;
- (b) filling the cavity with first and second liquids (44, 47) that are immiscible and of different refractive indices via the channel;
- and
- (c) hermetically sealing the channel.
Electrowetting-based variable-focus lens (10) comprising an enclosure that comprises a cavity (17) containing at least two immiscible liquids (44, 47) of different refractive indices, wherein the enclosure comprises at least one channel (27, 28;
- 59) communicating at one end with the cavity and at the other end emerging at the exterior surface of the lens, said channel being hermetically sealed by a plug (48, 49;
- 65, 66).
