电子光学仪器

高分辨本领电子光学仪器（例如电子显微镜）要求电子透镜具有严格的旋转对称性，但是实际的电子透镜存在着非旋转对称的缺陷，从而影响了仪器的质量。

Electron-optical instruments ( e.g. the electron microscope ) with high resolving power require strict rotational symmetry in its electron lens system .

这些结果可用于电子束器件、电子光学仪器和高能加速器中的聚焦或偏转或聚焦兼偏转元件的设计。

These results of this paper may be of use in designing focusing or deflection systems of electron ray devices , electron-optical instruments and high energy accelerators .

目前，高科技研究型显微镜（例如的透射电子显微镜、扫描电子显微镜）等光学仪器的调焦系统大部分都已经采用了自动调焦，有些配备数码照相系统，这些仪器价格昂贵。

Currently , high-tech research microscopes ( such as the transmission electron microscope , scanning electron microscope ) as optical instruments have used mostly auto-focusing system , and some microscopes equipped with digital photography system , the equipment is expensive .

医用电子内窥镜是一种可插入人体体腔和脏器内腔进行直接观察，诊断治疗的医用电子光学仪器。

The medical electronic endoscope is one kind of medical electronic optical instruments that may insert the human body cavity and the internal organs cavity to carry on the visual observation and the diagnosis treatment .
