Abstract
Because of the required lens motion in today’s optical zoom lenses, optical systems with zooming capability are more expensive and often more bulky and heavy than the systems without. The requirement for changing lens distance for zooming has become a roadblock for incorporating zooming features into systems that are cost sensitive or size-limited such as cellphones, PDAs, and notebook computers. For this reason, new design and technology for compact zoom lenses without lens motions are clearly desirable. Fluidic adaptive lenses, as reported by the authors previously [1–4], have the characteristics of wide focal length tunability and lens type convertibility. In this paper we show that the above characteristics of fluidic lenses fit uniquely to integrated zoom lenses that obtain zooming function without varying the lens distance.
