    • The invention relates to an adjustment method, especially for adjusting optical or fibre optical components. Said method involves locally heating, in a defined manner, at least one first partial region of an adjustment region (106, 114) of an actuator (100, 200, 400), in such a way that compressive strains appear in at least one second partial region of the adjustment region of the actuator (100, 200, 400) as a result of the fact that said second partial region prevents the thermal expansion of the heated partial area. When the yielding point σF of the material of the partial region is achieved, said compressive strains lead to a plastic deformation of the heated partial region. The heated first partial region shrinks during the cooling process, triggering a defined geometry modification of the actuator (100, 200, 400) following the cooling process. Due to the fact that the at least one second partial region prevents the shrinking, tensile stresses appear in the previously heated first partial region and the compressive strains are frozen in the at least one second region. According to the invention, the regions of the actuator (100, 200, 300, 400), in which the tensile stresses or compressive strains are frozen following the cooling process, are brought to a critical temperature (Tk) in relation to the operational temperature range of the actuator, after the cooling process, at least until the flow processes of the material at said critical temperature are largely completed. A second adjustment process is then carried out. The invention also relates to an actuator which is especially suitable for carrying out the inventive method, and an optical component comprising one such actuator.
    • 本发明涉及一种调整方法,特别是调整光学或光纤组件的方法。 所述方法包括以限定的方式局部加热致动器(100,200,400)的调节区域(106,114)的至少一个第一部分区域,使压缩应变出现在至少一秒钟 由于所述第二部分区域防止加热的部分区域的热膨胀,所以致动器的调节区域的部分区域(100,200,400)。 当实现部分区域的材料的屈服点σF 时,所述压缩应变导致加热的部分区域的塑性变形。 加热的第一部分区域在冷却过程中收缩,在冷却过程之后触发致动器(100,200,400)的限定几何修改。 由于至少一个第二部分区域防止收缩,拉伸应力出现在先前加热的第一部分区域中,并且压缩应变在至少一个第二区域中被冻结。 根据本发明,在冷却过程之后将拉伸应力或压缩应变冷冻的致动器(100,200,300,400)的区域达到临界温度(T >)相对于致动器的操作温度范围,在冷却过程之后,至少直到材料在所述临界温度下的流程大部分完成。 然后进行第二调整过程。 本发明还涉及特别适于实施本发明的方法的致动器,以及包括一个这样的致动器的光学部件。
