VARIFOCAL LENS STRUCTURE AND METHOD OF MANUFACTURING THE SAME

摘要

PURPOSE: A varifocal lens structure and a manufacturing method thereof are provided to change the thickness of a frame by forming the frame by using PDMS(Polymethylsiloxane) containing high heat expansion rate. CONSTITUTION: A fluid chamber is formed in a frame. The fluid chamber is filled with optical fluid. A transparent cover(120) is located at the upper side of the frame. An elastic membrane(130) is located at the lower side of the frame. An actuator(140) is located of the elastic membrane. The optical fluid and fluid have heat expansion rate higher than PDMS. The optical fluid and fluid contain a fluorine functional group. The thickness of the frame is same with the thickness of the optical fluid. Micro-bubbles are formed within the PDMS. The micro-bubbles are filled with the fluid. The diameter of the micro-bubbles is less than 10micrometers.
