ABSTRACT:
A method for detection of information on at least one optical element for monitoring an equipment, in which an electromagnetic radiation is shaped or guided by the at least one optical element, particularly for monitoring a laser arrangement. A change of at least one physical quantity in or on at least one optical element is detected with a measuring device by means of the absorbed electromagnetic radiation. At least one actual value detected by means of the measuring device is forwarded to an evaluation unit. At least one actual value is compared with a reference value deposited in the evaluation unit.
