it can magnify up to 500,000 times == == == == == Electron microscopes are expensive to build and maintain, but the capital and running costs of confocal light microscope systems now overlaps with those of basic electron microscopes. They are dynamic rather than static in their operation, requiring extremely stable high-voltage supplies, extremely stable currents to each electromagnetic coil/lens, continuously-pumped high- or ultra-high-vacuum systems, and a cooling water supply circulation through the lenses and pumps. As they are very sensitive to vibration and external magnetic fields, microscopes designed to achieve high resolutions must be housed in stable buildings (sometimes underground) with special services such as magnetic field cancelling systems. Some desktop low voltage electron microscopes have TEM capabilities at very low voltages (around 5 kV) without stringent voltage supply, lens coil current, cooling water or vibration isolation requirements and as such are much less expensive to buy and far easier to install and maintain, but do not have the same ultra-high (atomic scale) resolution capabilities as the larger instruments. The samples largely have to be viewed in vacuum, as the molecules that make up air would scatter the electrons. One exception is the environmental scanning electron microscope, which allows hydrated samples to be viewed in a low-pressure (up to 20 Torr/2.7 kPa), wet environment.
There is a compound light microscope, an scannignn electron microscope, and transmission electron microscope.

The four main types of microscopes are the Light Microscope, Electron Microscope, the Transition electron microscope and Scanning electron microscope.

Two types of electron microscopes are the scanning electron microscope, or SEM, and transmission electron microscope, or TEM.

The two big advantages are: 1. Magnification: the electron microscope can be used to visualize individual molecules and even atoms! 2. Resolution: The ability of a microscope to distinguish two closely lying points as separate entities.
An Electron microscope is more sophisticated. They use electrons and allow you to magnify objects up to 2000000x and view said objects in 3D.
