Patent ID: 7499222

Claim:
Method of manufacturing a collection of n separate variable focus lenses, wherein n≧2 and each variable focus lens comprise the following components: an electrically insulating member in which a through-hole is arranged for providing a light path through the electrically insulating member, which through-hole is sealed by means of covers which are optically transparent in the light path; a fluid chamber which is enclosed by an inner surface of the through-hole and the covers, and which is filled with a first fluid and a second fluid ( 52 ), which are non-miscible, and which are in contact over a meniscus; and a first electrode and a second electrode, wherein a shape of the meniscus is variable under the application of a voltage between the first electrode and the second electrode; the method comprising the following steps: providing an electrically insulating body, which is provided with at least n through-holes, wherein a part of a surface of the electrically insulating body is covered with electrically conducting material; covering a part of the electrically conducting material with an electrically insulating material; partially sealing n through-holes; filling the n partially sealed through-holes with the first fluid and the second fluid; completely sealing the n through-holes; and dividing the electrically insulating body into n portions.
