What is the maximum power of magnification of a microscope?
Actual magnification of light microscopes could reach up 1000x magnification depending on the type of light microscope. Light microscopes could be divided into brightfield microscope and phase-contrast microscope for viewing stained specimen and unstained specimen respectively. Magnification of electron microscope on the other hand could go up to 1000000x. The actual magnification as well depends on types of electron microscope which includes transmission-electron microscope and scanning-electron microscope where both of them are used in viewing internal cell structures and cell surface structures respectively.
What is the maximum magnification of a microscope?
one can make images of atoms using a scanning tunneling mcroscope.
What is the maximum resolution of the transmission electron microscope?
An electron microscope can magnify up to more than 1015 times. It is always in black and white but INSANELY detailed. It is black and white because electrons are negative(ELECTRON microscope).
Which microscope has a better resolution a light microscope or a electron microscope?
An electron microscope is capable of much higher resolution and greater magnification than a light microscope.Short Answer:Electron microscopes have much better resolution and are capable of much higher magnification than light microscopes because the wavelength of the electrons is thousands of times smaller than the wavelength of light.Light microscopes can typically resolve structures to a fraction of a micron compared to electron microscopes which in practice achieve resolutions of a few nanometers. Practically, electron microscope can have almost a thousand times greater resolution than an optical microscope.The useful magnification of an electron microscope is also in the range of a thousand times greater than an optical microscope.The actual performance of any microscope depends on its design and lensing system and so significant variation exists in the above practical characteristics and performance of both types of microscopes can be enhanced in various ways.Long Answer:An electron microscope uses an electron beam to illuminate a specimen and produce the image.An optical or light microscope uses a light beam to illuminate a specimen and produce the image.A microscope of either type is characterized by its magnification and resolving power. The magnification depends on the lensing system and can be increased to any degree, but the maximum useful magnification is limited by the resolving power.The resolving power of a microscope can not be better than the limits placed on it by the size of the wavelength of the illuminating beam. The smaller the wavelength, the smaller the structures that can be resolved in them image.Visible wavelengths of light are a few hundred nanometers. An electron microscope operates with electrons accelerated to a few hundred thousand electron volts of energy and with a wavelength in the range of few hundredths of an Angstrom.An electron microscope has a theoretical resolving power that is much greater than a light microscope and can reveal smaller structures because the electrons used have wavelengths (few hundredths of Angstroms) almost 100,000 times shorter than visible light (few hundred nanometers).An optimized electron microscope can achieve a practical resolution of a few Angstroms and a useful magnifications in the millions of times.A good light microscope can resolve structures smaller than a micron but is limited to about a few hundred nanometers resolution. The useful magnification of a light microscope is not much more than a thousand times.The electron microscope uses electrostatic and electromagnetic fields to act as lenses to control and focus the electron beam and to form an image. An optical or light microscope employs glass lenses.

What is the maximum magnification's of the scanning electron microscope?
The scanning electron microscope has a magnification range from 15x to 200,000x (reached in 25 steps) and a resolution of 5 nanometers.

What microscope would be used to study a specimen smaller than 0.2 micrometers?
The maximum magnification of a light microscope is 2000x. Anything requiring more than 2000x magnification requires an electron microscope.
What is the maximum magnification of a SEM?
A scanning electron microscope has a very large depth of field which makes the images produced appear three dimensional. Magnifications from 25X to 250,000X (250 times the magnification limit of a light microscope) are possible. Although my Science Text book says it can reach a magnification of 300 000X, but most specimens are easier to view at magnification less than 10 000X.
What type of microscope is used in hi-tech labs to achieve the best magnification?
Depending on the desired results, several types of scanning probe microscopes can be found in hi-tech labs to achieve the maximum magnification. These include atomic force microscope, scanning tunneling microscope, electrostatic force microscope, kelvin probe force microscope, magnetic resonance force microscope, and piezoresponse force microscope.
