<p>The objective (1) is fixed to a support (3) which is clamped by means of a screw (4) to a lateral rod (5). On the support (3) is another rod (6). The two rods (5, 6) form guidance elements. One end of the rod (5) is located in a bearing (7). A similar bearing (12) is fitted to the other end of the rod (5), this end of the rod is separated from the opposite end by a distance which exceeds a multiple of the supports length. The shortest rod (6) is contained in a bearing (15). The base chassis is fitted with adjusting means which permit orientation of the optical axis (17) of the objective on the casing of the system.</p> |
