ABSTRACT:
A liquid crystal cell (10) is formed with a hollow cylinder (12) and a solid cylinder (32) inserted into a hole (32) of the hollow cylinder (12) so that a first reference surface (34) of the solid cylinder (32) lies between a first reference surface (14) of the hollow cylinder (12) and a second surface (13) of the hollow cylinder (12). The first reference surface (14) of the hollow cylinder (12) and the second surface (13) of the hollow cylinder (12) are essentially parallel surfaces which are perpendicular to the axis of revolution (18) of the hollow cylinder (12). The solid cylinder (34) is affixed to the hollow cylinder (12) to maintain a fixed gap (38) between the first reference surface (14) of the hollow cylinder (12) and the first reference surface (34) of the solid cylinder (32). A third substrate (58) is in contact with the first reference surface (14) of the hollow cylinder (12) to establish a cavity (70) between the third substrate (58) and the first reference surface (34) of the solid cylinder (32) for confining a liquid crystal material in the cell (10).
