Microscope

The first microscope was conceived around year 1600, the actual inventor is unknown but it is believed to be the Dutch lens makers. Few decades later, Antonie van Leeuwenhoek discovered microbe with his  275x single lens microscope. The following centuries witnessed the evolution of microscope with breakthrough technologies such as Abbe condenser, abberation correction, Kohler illumination, phase contrast, DIC, electron microscope etc.  Today, electron microscope with mega magnification can observe in sub-nm resolution.

Optical Microscope vs Electron Microscope

Optical microscope (OM) uses photon (light), has a resolution limit of 200 nm (max around 1000x-2000x), offers quick and easy observation even on living specimen with colour information.
Electron microscope (EM) manages to observe in mega magnification and sub-nano resolution. However, the process is slower and costlier due to the destructive preparation. Higher depth of field image can be achieved using its electron beam though only rendered in greyscale.
