Lens Device and Method of Manufacturing the Same

Abstract

A lens device and a method of manufacturing the same are provided, wherein the lens device includes a transparent substrate, a metal layer, a hydrophobic layer and an aspherical lens. The metal layer is formed on the transparent substrate, and the hydrophobic layer is formed on the metal layer. The metal layer has a first opening, such that an area of the transparent substrate corresponding to the first opening is not covered by the metal layer. The hydrophobic layer has a second opening connected to the first opening, and the second opening is larger than the first opening, such that a portion of the metal layer adjacent to a peripheral edge of the first opening is not covered by the hydrophobic layer. The aspherical lens is formed on the area of the transparent substrate and contacts the portion of the metal layer.
