Abstract
Sočivo promenljive žižne daljine obuhvata prvu i drugu providnu, savitljivu membranu (2) koje su zategnute i obrazuju šupljinu (30) u kojoj je zaptivno smešteno providno silikonsko ulje (4). Podešavanjem pritiska ili zapremine ulja u šupljini menja se žižna daljina sočiva. Da bi se izradilo sočivo, periferija svake od membrana (2) spregnuta je izmedju dva prstena (8, 10; 10, 12) jedne grupe od tri medjusobno spregnuta prstena (8, 10, 12). Medjusobno spregnuti prstenovi su spojeni deformisanjem radi zatezanja membrana (2) i zaptivanja šupljine (30).[A variable focus lens comprises first and second transparent, flexible membranes (2) which are tensioned and which define a cavity (30) in which a transparent, silicone oil (4) is sealed. Adjustment of the pressure or volume of the oil in the cavity changes the focal length of the lens. To fabricate the lens, the periphery of each membrane (2) is engaged between two rings (8, 10; 10, 12) of a set of three interengaging rings (8, 10, 12). The interengaged rings are crimped together to tension the membranes (2) and seal the cavity (30).
