Scanning Electron Microscope (SEM):

Scanning Electron Microscope (SEM) is used to study the detailed architecture of cell surfaces. It uses an electron beam to scan the surface that has been coated with metal. When the beam hits the metal, it is not absorbed or transmitted. The electrons are reflected from the metal and are collected and used to produce an image. SEM doesn’t have great magnifying Power. It is about 10,000 to 100,000 times.
