The zoom lens system based on mems

The present application provides a microelectromechanical (MEMS) based zoom lens system, for applications such as micro-miniature electronic device or the like in the image forming apparatus. The MEMS-based zoom lens system comprising: at least four optical elements, lenses, or two or Lohmann Alvarez lens is configured such that an optical signal along an optical signal path through. Each MEMS optical element is driven and can be displaced in a direction substantially transverse to the optical signal path. In use, the lateral displacement of the optical assembly to change the total focal length of the zoom lens system of MEMS, for example, for providing an optical zoom function. On the other hand, it is also provided a method of manufacturing a MEMS zoom lens system.
