Lens device and method of manufacturing the same

摘要

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.

1. A method of manufacturing a lens device, the method comprising:
(a) providing a transparent substrate; (b) forming an electrode layer on the transparent substrate; (c) forming a first opening in the electrode layer for exposing an area of the transparent substrate via the first opening; (d) forming a hydrophobic layer on the electrode layer, wherein the hydrophobic layer has a second opening connected to the first opening, and the second opening is larger than the first opening for exposing a portion of the electrode layer adjacent to a peripheral edge of the first opening; (e) providing a liquid material of lens on the area of the transparent substrate, wherein the liquid material of lens contacts the portion of the electrode layer adjacent to the peripheral edge of the first opening for enhancing adhesion; (f) applying an electrostatic force to the liquid material of lens for adjust ing a shape of the liquid material of lens to be a liquid aspherical lens; and (g) curing the liquid aspherical lens to form a solid aspherical lens.
