A system of reflectors is used to form beam-expanding and collimating electro-optic transducer devices, including radiation sources and/or detectors. Preferably, the reflector system is of the Cassegrainian or Ritchey-Chretien type. Radiation such as light signals can be conducted to or from the transducers by fiber-optic cables. Alignment of optical conductors or 'cores' of the fiber-optic cables or the reflector system with a transducer is provided by coupling a magnetic member to the conductor or reflector system and applying a controllable magnetic field from outside of the device to provide alignment, and then fixing the components in place by the use of means such as light-curable epoxy resin.

Electro-optical transducer with multi-reflector beam-expanding and collimating input/output device

A system of reflectors is used to form a beam-expanding and collimating terminus and coupler for fiber-optic cables. Preferably, the reflector system is of the Cassegrainian or Ritchey-Chretien type. Alignment of optical conductors or &ldquo;cores&rdquo; of fiber-optic cables is provided by coupling a magnetic member to one core end and applying a controllable magnetic field from outside of the terminus to move the core into alignment position, and then fixing the core in place by the use of means such as light-curable epoxy resin. Use of this process in termini, couplers and splices is described.

Fiber-optic cable terminal connector and alignment device and method

Reflections from an air-to-solid interface in a multiple reflector optical device are suppressed by giving the output surface of the device a slightly curved refractive surface so as to deflect the reflections away from the optical axis of the device. The device is shown in use as a transducer input/output device, and as a fiber-optic cable terminus and coupler.

Reflection suppression in multiple-reflector collimation system

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.
