Microscopes are available in abundance….Not just in number but in size, shape and for different utility purpose.
Microscopes are obtainable from the single lens microscope to the urbane ones with imaging unit.
Microscopes vary on the basis of their tenacity, intensification, brightness method, type of image, field of view, grade of mechanization etc.
After reading this article, the microscope you find suitable according to your needs and requirement, start looking for it in the upcoming microscopes for sale on the internet.
Entire properties of microscopes depend on the radiation source of them. Microscopes can be generally defined as light, electron and confocal.
Light microscopes use visible light as the radiation source.
Light microscopes are of two types:
1) Stereo microscopes and
2) Compound microscopes.
a) Stereo microscopes: Stereo microscopes are better recognized as dissection microscopes, since they offer 3-dimensional view of the object.
b) Compound microscopes: This microscope offers 2- dimensional view of the object, which are used for laboratory purposes.
c) Phase contrast microscopes: These microscopes and dark field microscopes adapt the principles of light microscopy to improve visual quality of the specimen.
d) Oil immersion microscopes: In this microscope, oil is poured between the lens and specimen to upsurge the magnification.
This is not all, there are various kinds of microscope for performing different functions, which are:
• Electron microscopes are cultured types, which are specifically uses as a stream of electrons as the energy source instead of light. These can safeguard higher levels of intensification and are used efficiently in the fields of geology, medicine and archaeology.

• Transmission electron microscope is utilized for magnifying the internal details of a specimen with the help of an electron beam. The 3 dimensional image of the specimen’s superficial can be examined with the help of scanning electron microscope.
• Fluorescence microscopes excite the dyed specimen with particular radiation to provide a brighter image.
