Abstract

The present invention relates to a micro variable-focus lens system. It includes the following steps: (1). preparing step; (2). micro-photo forming step; (3). mold-transferring step; (4). plate forming step; (5). joining step; and (6). final product step. By using the U-V light and micro-photo technique, a flowing way mold block, a lens mold block and an extra mold block are formed on this plate. After using the flexible PDMS as a material, a lens mold can be obtained. Its flowing way is thinner than the lens portion. Then, a plate is formed and added with a solidifying agent. After hardening it, a variable-focus lens system is obtained. By adjusting the pressure of the fluid inside, the lens portion can be expanded to change its focus. So, this invention has the following functions: it has a flexible variable-focus system; it just has one joining procedure with low manufacturing cost; its lens portion can be changed; and its focus is adjustable.
