Types of Microscopes

Microscopes range from the uncomplicated singular lens microscope to 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.

Depending on the radiation source, microscopes can be broadly classified as light, electron and confocal. Light microscopes apply illustrated light as the radiation source. Light microscopes can be again classified into stereo microscopes and composition microscopes. Stereo microscopes are commonly known as dissection microscopes, which can supply a 3-dimensional view of the object. composition microscopes supply a 2- dimensional view of the objects that can be used for laboratory purposes. Phase disagreement microscopes and dark field microscopes modify the theory of light microscopy to improve optical ability of the specimen. Oil immersion microscopes use oil between the lens and specimen to growth the magnification.

Microscope

Electron microscopes are sophisticated types, which use a stream of electrons as the radiation source instead of light. These can ensure higher levels of magnification and are used effectively in the fields of geology, medicine and archaeology. Transmission electron microscope is used to magnify the internal details of a specimen using an electron beam. The 3 dimensional image of the specimen's exterior can be analyzed using scanning electron microscope. Scanning transmission electron microscope is a modification of Tem, which scans the object at a faster rate. Confocal microscopes are very automated, and apply laser as the radiation source. Fluorescence microscopes excite the dyed specimen with singular radiation to supply a brighter image.

Scanning probe microscopes are a group of microscopes, which form images by scanning the specimen using a physical probe. Scanning probe microscopes in general contain 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 are also available. The inference microscope is used with perfectly transparent objects that are indiscernible under an commonplace microscope.

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