<p>The system (1) has an optical unit (2) cooperating with an optical lens (3), which is accommodated by a support arrangement (4) at a distance (d) from the optical unit. An optical path extends along an optical axis and has a focal point via the optical lens in a plane of the optical unit. The support arrangement has a compensation body (6) whose thermal expansion coefficient is formed such that thermal expansion caused changes of a focal plane of the optical path relative to the optical unit is compensated by mechanical effects of the compensation body.</p> |
