电子显微镜（ｅｌｅｃｔｒｏｎ ｍｉｃｒｏｓｃｏｐｅ） 电子显微镜是一种利用电子束照射物体并形成像的非光学显微镜．电子束通过作为电子折射媒质的静电透镜或磁透镜进行聚焦，通过加速电压，能够产生波长比普通光要短若干倍的电子波．根据显微镜原理，波长愈短，其分辨本领
An electron microscope An electron microscope is a non-optical microscope that uses an electron beam to illuminate an object and form an image. The electron beam is focused by an electrostatic lens or a magnetic lens as an electron refractive medium, and an electron wave whose wavelength is several times shorter than that of ordinary light can be generated by accelerating the voltage. According to the microscope principle, the shorter the wavelength, its ability to distinguish
