Abstract
There is presented a fiber-optic bundle and collimator assembly comprising plurality of bodies of cylindrical configuration and of equal diameter arranged side by side in a hexagonal close-packed configuration, a retainer for retaining the bodies in the close-packed configuration, and a potting material for locking the bodies in position. A plurality of the bodies and fiber-optic ferrules have therein a single optical fiber. A remainder of the bodies are non-optical fiber bearing ferrules in alignment width-wise of the assembly to form a collimator assembly face. The fiber-optic ferrules are each recessed from the assembly face to form a pocket. A spacer is disposed in each pocket and abuts a fiber-optic ferrule, and a spherical lens is disposed in each pocket and abuts a spacer. Each of the lenses is of the same diameter as its associated fiber-optic ferrule, and has its axis in alignment with the axis of the associated fiber-optic ferrule optical fiber.
