通过扩展显微镜技术，设计了有限元设计的远心光学系统，研制了厘米级局部磁化方向的磁域观察系统。该系统实现的视场为1.40×1.05 cm，抑制了散焦和失真。通过从两个正交方向进行纵向克尔观测，可以检测局部磁化方向。该系统可用于非晶箔带材、软磁薄膜等软磁材料表面粗糙样品的磁域观测和时间分辨分析。
An observation system of centimeter-order of view of magnetic domain with local magnetization direction was developed by designing a telecentric optical system of finite design through the extension of microscope technology. The field of view realized in the developed system was 1.40 × 1.05 cm as suppressing defocus and distortion. Detection of the local magnetization direction has become possible by longitudinal Kerr observation from the orthogonal two directions. This system can be applied to the domain observation of rough surface samples and time resolved analysis for soft magnetic materials such as amorphous foil strips and soft magnetic thin films.
