Abstract
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.
