电镜相机故障诊断及维修一例

One case of fault diagnosis and maintenance of electron microscope camera

电镜相机是透射电镜的重要组件,常常用于材料和组织细胞的观察。相机采用光电信号转换原理产生图像。相机闪烁体表面要求洁净,不能有污染物,若有污染物会对图像质量产生影响。本文介绍一例电镜相机的维修案例,分析故障现象产生原因及排除,最后对本案例进行分析讨论。

The electron microscope camera is an important component of transmission electron microscopy,often used for observing materials and tissue cells.Based on the principle of photoelectric signal conversion,the camera generates images.The surface of the camera's scintillator must be clean and free of pollutants,which can affect image quality.This article introduces a maintenance case of an electron microscope camera,analyzes the causes of the failure and complete troubleshooting,and finally analyzes and discusses this case.
