<p>The method involves implementing an optical element in a direction from a heat generating radiation and implementing in another direction (18) for the determination of the characteristic changes of the optical element from a measuring radiation (16). The measuring radiation is aligned to the optical element in such a way that the latter direction runs transverse to the former direction. An independent claim is included for an arrangement for determination of thermal-conditioned characteristic change of an optical element.</p> |
