Understanding Dissecting Scope Features



Most of the other contemporary microscopes have a standard magnification that is much greater than that of a dissecting microscope but the dissecting scope is still regarded a superior instrument for carrying out visual examinations. The general perception is that the lack of magnification should make the dissecting scope less useful than compound microscopes but this isn't so. The lack of magnification is further interlinked with a host of features that make the dissecting scope advanced over most other scopes. In fact, it offers better visual status on the same specimen and that too at much lower magnification.



The dissecting microscope is able to functional differently and effectively due to its unorthodox construction. Here, the light source is externally located. The light source is directed from an object called the illuminator. This device is used for lighting-up the specimen in a particular manner. Due to its much bigger size, the dissecting microscope can be used for examining the biggest of specimens that are deemed impractical for other microscopes. The superior view offered by the dissecting microscopes is due to its ability to present the images in a 3D-like format. Due to this, though magnified to a lesser extent, the images are clearer and easier for observation. This type of magnification is now called surface magnification since it magnifies the entire surface under the observation lens. This is a major improvement over the conventional scopes wherein only a part of the sample can be visually amplified and that too, in very small sections. Due to the lower magnification feature of dissecting microscopes, the examiners can view a larger visual field at the same time.

The dissection microscope is capable of presenting a 3D image that is only a hundred times bigger than the actual sample but the clarity supersedes the vision offered by other scopes. The vision offered by the dissection microscope is called binocular vision. This is the reason why the images seem so enormous despite being under lower magnification and the overall clarity is much greater. Further, the presence of the external lighting source means that the most opaque or difficult-to-visualize samples can be easily converted into images that are clear. Despite its much bigger size, the specimen-holding surface of dissecting scopes is so accommodating that the smallest of live samples can also be placed and examined.
