Posted in Unspecified


Microscopes add some simple single lens microscope for the sophisticated ones with imaging systems. Microscopes differ on the basis of their resolution, magnification, illumination method, type of image, field of view, degree of automation etc.

With regards to the radiation source, microscopes could be broadly regarded as light, electron and confocal. Light microscopes utilize visible light as the radiation source. Light microscopes may be again classified into stereo microscopes and compound microscopes. Stereo microscopes are commonly called dissection microscopes, which can provide a 3-dimensional view of the thing. Compound microscopes give a 2- dimensional check out the objects that can be used for laboratory purposes. Phase contrast microscopes and dark field microscopes customize the principles of sunshine microscopy to improve visual company's specimen. Oil immersion microscopes use oil between your lens and specimen to raise the magnification.


Electron microscopes are sophisticated types, which use a stream of electrons since the radiation source as opposed to light. It may ensure higher degrees of magnification and so are used effectively within the fields of geology, medicine and archaeology. Transmission electron microscope is employed to exaggerate the inner information a specimen employing an electron beam. The 3 dimensional picture of the specimen's surface can be analyzed using scanning electron microscope. Scanning transmission electron microscope can be a modification of TEM, which scans the thing at a quicker rate. Confocal microscopes are highly automated, and apply laser because the radiation source. Fluorescence microscopes excite the dyed specimen with particular radiation to give a brighter image.

Live cell imaging

Scanning probe microscopes certainly are a group of microscopes, which form images by scanning the specimen employing a physical probe. Scanning probe microscopes mainly include scanning tunneling microscopes, atomic force microscopes, near-field scanning optical microscopes etc. These have great applications in nanotechnology. Microscopes based on magnetic force, microwave, acoustics etc can also be found. The inference microscope is used with perfectly transparent objects that are invisible under an ordinary microscope.

In day-to-day use, microscopes are classified on the basis of the number of their lenses, i.e., monocular, binocular and trilocular.
