Abstract
A light beam deflecting apparatus is provided for diverting a light beam from an initial path. The apparatus includes first and second substantially transparent plates. The light beam passes through the first and second plates when the first and second plates are positioned in the path of the beam of light. A connector is attached to the first and second plates for connecting the plates to one another and for permitting the plates to be displaced relative to one another. A bellows enclosure is attached to the outer edges of the first and second plates for encasing the first and second plates to form a reservoir therewith capable of supporting a fluid therein. A fluid is filled within the reservoir and causes the light beam to deviate from its initial path when the first and second plates are located in the path of the light beam and are positioned in a non-parallel position.
