Abstract
Abstract Fiber optic variable focus lens in which a bundle of fibers are fixed at end in a common plane and having another end of the fibers that is adjustable relative to a ring to allow said another end of the fibers to be adjusted to end in different planes and produce a lens. The lens can be varied and adjusted by utilizing adjusting mechanism for the fibers.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
111 words
A fiber optic variable focus lens comprising a bundle of optical fibers of uniform length, rings mounted at opposite ends of the bundle, one of said rings being mounted at one of the ends of said optical fibers in a fixed relationship to the optical fibers to prevent movement of said one end of said optical fibers relative to said one of said rings, the other of said rings being mounted relative to the other end of said fibers for sliding longitudinal freedom of the other end of each fiber relative to said other of said rings to allow said fibers to be adjusted so as to be in different planes.
Claim 2
Dependent Claim
111 words
A fiber optic variable focus lens comprising a bundle of optical fibers of uniform length, rings mounted at opposite ends of the bundle, one of said rings being mounted at one of the ends of said optical fibers in a fixed relationship to the optical fibers to prevent movement of said one end of said optical fibers relative to said one of said rings, the other of said rings being mounted relative to the other end of said fibers for sliding longitudinal freedom of the other end of each fiber relative to said other of said rings to allow said fibers to be adjusted so as to be in different planes.
Claim 3
Dependent Claim
41 words
A fiber optic variable focus lens as set forth in claim 1, wherein adjusting mechanism is mounted relative to said fibers for adjusting said fibers relative to said other of said rings to adjust the focus of the variable focus lens.
Claim 4
Dependent Claim
21 words
A fiber optic variable focus lens as set forth in claim 2, wherein said adjusting mechanism is an electromechanical adjusting mechanism.
