WebScanning electron microscopy, or SEM, produces detailed, magnified images of an object by scanning its surface to create a high resolution image. SEM does this using a focused beam of electrons. The resulting images show information about what the object is made of and its physical features. The instrument which obtains this information about ... WebSEMs usually use acceleration voltages up to 30 kV, while TEM users can set it in the range of 60–300 kV. The magnifications that TEMs offer are also much higher compared to SEMs. TEM users can magnify their samples by more than 50 million times, while for the SEM, this is limited to 1–2 million times.
