A SYSTEM OF REFLECTORS IS USED TO FORM A BEAM-EXPANDING AND COLLIMATING TERMINUS AND COUPLE FOR FIBER-OPTIC CABLES (26) AND ELECTRO-OPTIC TRANSDUCER DEVICE, INCLUDING RADIATION SOURCES AND/OR DETECTORS. ALIGNMENT OF OPTICAL CONDUCTORS (270) OR "CORES" OF THE FIBER-OPTIC CABLES (26) OR THE REFLECTOR SYSTEM (178) WITH A TRANSDUCER (208) IS PROVIDED BY COUPLING A MAGNETIC MEMBER (172) TO THE CONDUCTOR OR REFLECTOR SYSTEM (178) 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. A MULTIPLE-REFLECTOR COLLIMATOR AND BEAM SPREADER IS ALIGNED WITH A SOURCE POINT BY VISUAL MEANS, IN ADDITION TO OR INSTEAD OF AN ELECTRICAL DETECTOR, IN ORDER TO AVOID THE NEED TO SEND A SIGNAL THROUGH THE SYSTEM TO A DETECTOR IN ORDER TO ALIGN THE COMPONENTS. REFLECTIONS AT 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 (77) OF THE DEVICE.
