Microscopes vary between the simple single lens microscope to the sophisticated ones using imaging methods. Microscopes differ on the basis of their resolution, magnification, lighting method, type of image, the field of view, the level of automation etc..
Based on the radiation origin, microscopes can be broadly classified as light, electron and confocal. Light microscopes utilize visible light as the radiation source. Light microscopes could be classified into stereo microscopes and chemical microscopes.
Stereomicroscopes are popularly known as dissection microscopes, that may provide a 3-dimensional view of the object. Compound microscopes offer a 2- dimensional view of these items which can be utilized for lab purposes. Phase contrast microscopes and dark field microscopes modify the principles of light microscopy to increase the visual quality of the specimen. Oil immersion microscopes utilize oil between your lens and specimen to raise the magnification.
Electron microscopes are complex types, that work with a flow of electrons while rays origin instead of light. These can ensure higher degrees of magnification and can be used efficiently within the fields of geology, medicine, and archaeology.
Transmission electron microscope is used to magnify the inner details of a noun with the electron beam. The 3-dimensional image of the specimen’s surface may be analyzed using scanning electron microscope. Scanning transmission electron microscope can be an alteration of TEM, which examines the object at a faster rate.

Confocal microscopes are highly automated and utilize laser because of the radiation source. Fluorescence microscopes excite the colored specimen with particular radiation to offer a brighter image.
Scanning probe microscopes are a group of microscopes, which shape images by scanning the specimen using an actual probe. Scanning probe microscopes chiefly include scanning tunneling microscopes, atomic force microscopes, near field scanning optical microscopes etc..
All these have great applications in nanotechnology. Microscopes based on magnetic force, microwave, and acoustics etc are also available. The inference microscope can be combined in combination with absolutely transparent objects that are invisible under an ordinary microscope.
