What’s the difference between an electron microscope and a light microscope? What size
particles can each see?

  1. Electron microscopes are massive and expensive coming to 3,000 dollars and up on eBay. There are four kinds of electron microscopes: transmission, scanning, reflection, and low- voltage. For the scanning electron microscope it needs to have a room without electric, magnetic, or vibration interference. It needs maintenance with cool water and a steady voltage. People need training to handle a SEM. A light microscope comes in two kinds: compound and stereo. They are also inexpensive as they are sold for about 20 dollars on eBay. For specimens the light microscopes use glass slides or nothing at all. The SEM uses aluminum stubs coated in gold while the TEM uses thin films of collodion on copper grids (Stevenson, n.d.)
