Abstract
A variable focal length microlens system having a base section with a fluid chamber and a fluid pressurization mechanism. A flexible, substantially transparent polymer lens section is fixed above the fluid chamber and the lens section has a curvature providing an initial focal point when in an unstrained state. The fluid chamber is substantially sealed and the fluid pressurization mechanism includes a flexible wall in the base section. The flexible wall may be displaced by magnetic activation, PZT activation of another activating mechanism.
Claims23
A variable focal length microlens apparatus comprising:
- a. a lens frame comprising a first surface and a second surface, with a view aperture formed through said first and second surfaces;
- b. a fluid chamber formed between said first and second surface;
- c. a flexible, substantially transparent polymer lens section positioned over said view aperture on each of said first and second surfaces;
- and
- d. a fluid pressurization mechanism capable of causing an increase or a decrease of fluid pressure in said fluid chamber, thereby adjustably forming a DCV lens or a DCX lens comprising a focal length range which can vary between about 1.5 mm and about 16 mm.
A variable focal length microlens apparatus comprising:
- a. at least two lens frames, each lens frame comprising a first surface, a second surface, with a spacer positioned therebetween and a view aperture formed through said first and second surfaces and said spacer;
- b. a fluid chamber formed between said first and second surface;
- c. a flexible, substantially transparent polymer lens section positioned over said view aperture on each of said first and second surfaces;
- d. a fluid pressurization mechanism capable of causing an increase or a decrease of fluid pressure in said fluid chamber, thereby adjustably forming a DCV lens or a DCX lens;
- and
- e. wherein said lens frames are positioned adjacent to one another in order to form a series of DCV and/or DCX lens and said lens frames communicate with a common fluid transfer path.
