ABSTRACT:
A wedge/taper alignment ring is used to hold the objective lens of a laser light pen in place. The ring is free to move in the axial direction under forces of thermal expansion and shock, decreasing distortion and misalignment to the objective. Moreover, it centers the mechanical axis of the objective to that of the housing. A spring with a high restoring force moves the ring back into place.
