Abstract
The present invention provides optical systems, devices and methods which utilize one or more electroactive films to adjust an optical parameter of the optical device/system.
Claims23
An optical device comprising:
- a two ply transparent/translucent membrane where a perimeter of each ply of the transparent/translucent is sealed to define a chamber containing an optical fluid therein;
- at least one electroactive film comprising a dielectric layer and two electrode layers, wherein at least a portion of the dielectric layer is sandwiched between the electrodes, the electroactive film located at the perimeter of the transparent/translucent membrane;
- and
- wherein activation of the at least one electroactive film affects a dimension of the transparent membrane.
1 more element
An optical system comprising:
- at least one fluidic lens;
- and
- at least one electroactive film associated with the at least one fluid lens, wherein activation of the at least one electroactive film affects a focal length of the fluidic lens wherein a diameter dimension of the fluidic lens is unaffected by activation of the at least one electroactive film.
An optical system comprising:
- a focusing lens element;
- and
- an afocal lens element positioned relative to the focusing lens;
- wherein at least one of the lens elements comprises at least one fluidic lens and at least one electroactive film associated with the at least one fluidic lens for adjusting an optical parameter of the system wherein the position of the afocal lens element relative to the focusing lens element remains constant upon activation of the at least one electroactive film.
1 more element
An optical system comprising:
- a focusing lens element:
- and
- an afocal lens element positioned relative to the focusing lens;
- wherein at least one of the lens elements comprises at least one fluidic lens and at least one electroactive film associated with the at least one fluidic lens for adjusting an optical parameter of the system wherein the afocal lens element further comprises at least two other lens elements wherein the at least one fluid lens is positioned in between the two other lens elements.
1 more element
An optical device comprising:
- at least one electroactive film comprising at least one opaque region and at least one transparent/translucent region, wherein activation of the at least one electroactive film changes a surface area of the transparent/translucent region relative to a surface area of the opaque region, wherein such change modulates the amount of light passing through the at least one transparent/translucent region.
