どちら は より良い, 顕微鏡 または 電子 顕微鏡?
For applications in biology, the resolving power of an optical microscope is far inferior to that of an electron microscope, because the resolution of an optical microscope is limited by the diffraction limit, so its resolution cannot be less than half the wavelength of the incident light. That is to say, if incident light of 400nm is used, the observed object cannot be smaller than 200nm. However, because it can perform real-time and dynamic observation, its status in biology is unparalleled. It is impossible to leave optical microscopes such as fluorescence microscopes and confocals in the field of biology. Since the electron microscope uses electron beams to scan and image, its resolution can easily reach the nanometer level, which is irreplaceable for the application of high-resolution imaging.
In the アプリケーション of 金属組織 分析, the 倍率 of the 電子 顕微鏡 is far higher than that of the 光学 顕微鏡 the max magnification of the modern electron 顕微鏡 has 超過 3 百万 倍, while the max 倍率 of the 光学 顕微鏡 is 約 2000 times. 顕微鏡 缶 直接 観察 the atom of some 重 金属 そして the きちんと 配置 原子 格子 in 結晶。
