Abstract
In an optoelectronic assembly in which one or more beam paths are to be aligned with a corresponding number of active optical elements, the cooperation between flexible alignment features and fixed alignment features achieves elastic averaging so as to provide the target accuracy. By averaging dimensional and positional errors over a large number of localized couplings of the flexible and fixed alignment features, elastic averaging provides the same accuracy as the more costly and complex kinematic alignment techniques.
