Abstract
A body is configured for alignment to a substrate having an alignment feature. The body includes an alignment structure defining a viewing surface, and a dedicated lens adapted to focus an image of the substrate's alignment feature through an optically-clear material of the body and onto the viewing surface. In the fiber optic context, a lens body is provided for optically coupling a substrate's OED to a corresponding optical fiber. The lens body further includes at least one active lens adapted to cooperate optically with a respective OED. The dedicated lens is positioned externally to any optical path. An optical subassembly includes a substrate having at least one perceptible alignment feature provided in a predetermined spatial relationship to the OED, and a lens body secured to the substrate such that the image of the substrate's alignment feature appears aligned relative to the viewing surface.
