<p>Phase shift element (5) and deflection element (7) are each fitted on outisde (4,6) of separate parts (2,3). Both elements can rotate about common rotataion axis within presettable rotation angle (alpha). Two further outsides (8,9) of both parts are slidable against each other and rotation axis may be at right angle light impingement plane of phase shift element.</p> |
