Its electron microscope with heighest resoluting power.
A microscope that uses electrons instead of photons to enhance soon and resolution.
The resolution of an optical microscope is not better (or worse) when using natural light. Resolution is determined by the numerical aperture (NA) of the objective.Why a vacuum in an electron microscope?The molecules that make up air would scatter the electrons in the electron beam
Blue wavelengths provide better resolution.
The transmission electron microscope operates on the same principle as the light microscope but uses electrons instead of light. What you can see with a light microscope is limited by the wavelength of light. Transmission electron microscopes use electrons as "light source" and their much lower wavelength makes it possible to get a resolution a thousand times better than with light microscope.
It uses an electron beam. An electron microscope is a type of microscope that uses an electron beam to magnify and illuminate a specimen. An electron microscope has greater resolving power than a light microscope and can reveal the structure of smaller objects because electrons have wavelengths about 100,000 times shorter than visible light photons. They can achieve better than 50 pm resolution and magnifications of up to about 10,000,000x whereas ordinary, non-confocal light microscopes are limited by diffraction to about 200 nm resolution and useful magnifications below 2000x.

Electron microscope.Transition microscope has a magnification of *500,000 and resolution of 0.5nm.
a microscope's resolution specifies the smallest object you can see and distinguish from other nearby objects.
The electron microscope because Electron microscopes can obtain pictures of extremely small objects-- much smaller than those that can be seen with light microscopes.
