Abstract
A lens module includes a lens barrel, at least one fixed focus lens fixed in the lens barrel, and at least two variable focus lenses fixed in the lens barrel. Each variable focus lens includes two electrodes and an electro-optical material between the electrodes. Each electrode is electrically connected to a voltage supply so as to be able to selectively apply a voltage to the electro-optical material and to thus selectively control the refractive index of that material. By changing the refractive index, a concordant change in the focus of a given variable focus lens is possible, without modifying the position and/or shape thereof.
Claims15
A lens module, comprising:
- a barrel;
- at least one fixed focus lens received in the lens barrel;
- and
- at least two variable focus lenses fixed in the lens barrel, each variable focus lens including two electrodes and an electro-optical material filled between the respective electrodes, each electrode being electrically connected to a voltage supply and thereby configured for applying a voltage to the electro-optical material;
- wherein each electrode includes a plurality of spaced concentric annular rings with varying radiuses and widths, the widths of the rings decrease as the radius of the rings decrease, and ring spaces between every two neighboring rings decrease in the direction of radius decrease.
A camera module, comprising:
- an image-receiving element;
- and
- a lens module configured for focusing an image upon the image-receiving element, the lens module comprising:
- a barrel;
- at least one fixed focus lens received in the lens barrel;
- and
- at least two variable focus lenses fixed in the lens barrel, each variable focus lens including two electrodes and an electro-optical material filled between the respective electrodes, each electrode being electrically connected to a voltage supply and thereby configured for applying a voltage to the electro-optical material;
- wherein each electrode includes a plurality of spaced concentric annular rings with varying radiuses and widths, the widths of the rings decrease as the radius of the rings decrease, and ring spaces between every two neighboring rings decrease in the direction of radius decrease.
