WebbThe most powerful light microscopes can resolve bacteria but not viruses. To see anything smaller than 500 nm, you will need an electron microscope. Electron microscopes shoot a high-voltage beam of electrons onto or through an object, which deflects and absorbs some of the electrons. WebbIf the microbe occupies 6 O.D. in length, then length of microbe = 6 x calibration factor = 6 x 2 = 12 µ. It is possible to measure the size of microbes by directly observing them on a stage micrometer. This would avoid calibration and calculations.
