<p>This device is comprised of an annular base plate (1), an intermediate annular body (2) mounted coaxially and with the possibility of rotation with respect to the previous one, a glass-holder platform (3) mounted on the intermediate body (2) with the possibility of lateral tilting in at least two perpendicular directions and some adjustment means to carry out the controlled tilting of the glass holder platform (3), to achieve the alignment of the optical axis (71) of the glass (7) mounted on it, with the mechanical axis (12) of the intermediate annular body (2) and of the base plate (1) permitting the rotation of the glass (7) the orientation of its optical axis remaining invariable. <IMAGE></p> |
