Why does TEM have higher resolution than SEM?

I figured I would clear this up. First lets talk about the other two answers, what does TEM stand for again? NOT, tunneling electron microscope, TEM actually is transmission electron microscopy. SEM is scanning electron microscopy. read more

In general, TEM has a higher resolution than SEM by a factor of 10 or more. The reason has to do with the way magnified images are formed in the two instruments. In a TEM, a nearly parallel beam of electrons travels through a thin specimen, and the resulting image is magnified electron-optically by a series of electromagnetic lenses, the main one of which is the objective lens. read more

Resolution: Electron microscopes have much higher resolution than light microscopes due to the shorter equivalent wavelength of electron beams compared with visible light. Magnification: Electron microscopes have much higher magnification than light microscopes. read more

The electrons used in electron microscopy (EM) have a much shorter wavelength, more like 0.0025 nm. Resolution in EM is typically limited by the quality of the lenses. read more
