Abstract
An apparatus for steering a light beam having a first lens element, a second lens element, a spacer element and a lubricative optical fluid. The first lens element has a convex lens surface. The second lens element has a concave lens surface. The concave lens surface is placed adjacent the convex lens surface of the first lens element. The spacer element is placed between the convex lens surface and the concave lens surface for maintaining the first and second lens elements at a fixed distance from each other. The spacer element also defines a generally incompressible gap between the first and second lens elements, yet allows the first and second lens elements to move with respect to one another. The lubricative optical fluid is disposed within the gap.
