Abstract:
1. An assembly comprising: an optical cell apparatus comprising: a hollow tubular body comprising a wall of the optical cell apparatus, the tubular body having longitudinally spaced first and second body ends and surrounding a longitudinal axis of the optical cell to define a member lumen therethrough; a first end member that is substantially rigid and attached to the first body end to define a first optical cell end; a first optical element, located within the member lumen and fixedly attached to the first end member; a second end member that is substantially rigid and attached to the second body end to define a second optical cell end; and a second optical element, located within the optical cell and fixedly attached to the second end member; and a first actuator mounted external to the member lumen and coupled to the first and second end members externally to the member lumen, the first actuator configured to apply a force to displace the first end member relative to the second end member in a direction substantially parallel to the longitudinal axis, the displacement sufficient to elastically deform the hollow tubular body of the optical cell apparatus such that a longitudinal distance between the first optical element and the second optical element is responsively altered.
