Abstract
A lens particularly for applications requiring a large lens eliminates costly grinding and polishing operations. The lens embodies an adjustable chamber containing an optical fluid which can be pressurized in varying degrees by altering the size of the chamber. Resilient optical diaphragms at the ends of the chamber have their curvatures changed responsive to changes in the pressure of the fluid in the chamber to produce a lens of fixed or variable focal length.
Claims11
An optical lens comprising a pair of telescopically interfitting threaded sleeves adapted for relative movement axially in response to turning, a pair of resilient optical diaphragm elements secured to and closing the outer ends of said sleeves and defining therewith a closed variable chamber, and an optical fluid filling said chamber between said diaphragm elements and being pressurized in varying degrees by adjustments of said sleeves and the pressure of said fluid acting directly on said diaphragm elements to impart thereto varying degrees of curvature.
