Uses of Dissecting Microscopes
Aside from dissecting laboratory experiments, dissecting microscopes are also used for a wide variety of microscope activities. These low power microscopes can be used for simple microscope activities such as observing coin and stamp collections as well as looking at items found in nature such as insects, rocks and many other things that children can find. These types of dissecting microscopes are also called kid microscope or student microscopes because of its child-friendly nature. Elementary as well as high schools use this type of microscope for their science laboratory classes.
While dissecting microscopes are called in such a name because of its being frequently used in dissecting operations, low power microscopes can also be called in different names depending on the kind of application that it is being used in. For example, forensic comparison microscopes are also low power microscopes that are used in the field of forensic science. Comparison microscopes are two separate microscopes that are connected by a single optical bridge. Sample evidences being observed such as bullet fragments, fingerprints, hair samples, thread samples, surface markings, wires and many others are seen through a slit image so that the viewer can see the both samples simultaneously.
There are also specialized low power dissecting microscopes such as the gemological microscope as used by gemologist for studying and grading gemstones. The standard illumination used by most microscopes is the bright field illumination wherein a full cone of light is directed on the sample. Gemological microscopes, however, utilize a darkfield condenser that blocks the light from directly focusing on the specimen. The darkfield condenser instead channels the light to the sides so that the specimen is illuminated from the sides against a very dark background. This results to a clear and brightly illuminated specimen. A high intensity halogen bulb is also used for this kind of low power microscope. Gem microscopes are used to view the surfaces of gemstones as well as in gemstone grading and evaluation.
A typical stereoscope would be considered low power. It may be used for looking at shiny flat surfaces for inspection. However, if the magnification required is too great, then a high power microscope such as a metallurgical would be used. Metallurgical microscopes are a type of compound microscope that is used for viewing highly polished surfaces like that of a metal or an alloy at greater magnification than the simple stereoscope has. This type of analysis cannot be done by a simple low power microscope because the magnification power is still not enough. Metallurgical microscopes are also used in looking for crystal defects as well as identifying and understanding the properties of crystals. Gemology (the study of gemstones) also uses metallurgical microscopes for its applications.
Though limited, dissecting microscopes can also be used in some biological applications such as examining microbiological cultures up close as well as tiny surgical biopsies and many more. Dissecting microscopes that are used in surgery are called operating microscopes and these are modified based on what type of surgery is being performed. The provide the surgeon with a 3D stereoscopic view of the operation.
Dissecting microscopes are low power microscopes that are widely used in examining surfaces. These microscopes are stereoscopic which means that it has two separate lenses that feed a subtly different image on each eye so that the resulting image will be in three-dimensional perspective. This gives a depth of focus on the image which is very advantageous on many kinds of applications. Prices vary depending on quality and features. They come in binocular and trinocular versions. The higher grade models have zoom magnification, some having greater zoom ranges than others. Be sure to review all your needs before buying one.
