Abstract

The invention relates to an adjustment method, especially for adjusting optical or fiber optical components. According to an embodiment of the invention, a first adjustment process is carried out in which, after a cooling process, the regions of the actuator in which the tensile stresses or compressive strains are frozen following the cooling process are brought to a critical temperature in relation to the operational temperature range of the actuator, at least until the flow processes of the material at said critical temperature are largely completed. A second adjustment process is then carried out.
