Alignment of a laser apparatus is achieved by actively aligning components of the laser apparatus and then passively deriving an optical axis from that alignment. This passive derivation can be achieved by identifying features of an actively aligned optical element, deriving positional data for those features, and developing an optical axis from that positional data. The derivation of positional data may be performed over a particular coordinate system of an image taken of the feature, e.g., obtained by a vision system. The positional data and optical axis may be extrapolated out to a reference coordinate system for use in passively aligning other optical elements.
