The camera length of electron diffraction in transmisson electron microscopy is one of the main technical parameters in designing electron microscope and the electron diffraction analysis to microcrystal sample. According to Bragg law, the formula of calculating TEM electron diffraction camera length is derived from the research on the ray path of electron diffraction images in TEM and the comparison on electron diffraction with ordinary electronic diffractometer. The difference of physical significance of electron diffraction camera length between TEM and ordinary electronic diffractometer is discussed.
透射式电子显微镜(Transmisson Electron Microcopy, TEM)中的电子衍射相机长度,是电子显微镜设计和对微晶体样品进行电子衍射分析的主要技术参数之一依据布拉格定律,经对TEM中电子衍射成像光路的探讨与研究,并通过TEM与普通电子衍射仪的电子衍射的对比分析,导出了TEM电子衍射相机长度的精确计算公式,阐述了TEM和普通电子衍射仪的电子衍射相机长度所表征的物理意义的区别。
