Abstract
Since only relatively small-area prism sub-plates can be manufactured in warp-free fashion, large area prism plates are formed of a plurality of sub-plates. A connection of the sub-plates must be stable and the expense for joining the sub-plates should be as low as possible. To create the large-area prism plate, adjoining sub-plates are connected to one another in two dimensions by at least one positive lock plug-type connection comprising locking projections and locking projection receptacleswhich form plug-type connections secured by latching devices which do not allow a dislocation of the joined sub-plates in a third dimension.
