Summary
A microscope is a biological instrument designed to give finer details of an object that an observer could not see using naked eyes or a hand lens. An object under observation is a specimen. There are several types of microscopes including the light microscope…

To clean dirty lenses, the observer should use a special lens tissue cleaning paper. Alternatively, an observer can use the common tissue paper moistened with ethanol (Hartley and Gregory, 1964, 111). V. To clean other parts of the microscope, the observer can use a tissue paper or a soft cloth. VI. Before the observer starts using a microscope, he should make sure that the low power objective lens click into position in line with the eyepiece. He should also do this after using the microscope. VII. The observer should not wet any part of the microscope. VIII. The observer must always clean and store the microscope at a safe place free from dust and moisture. Functions of parts of a microscope The limb or the arm supports the body tube and the stage. The base- It gives affirm and steady support to the entire microscope. The Body tube- it holds the eyepiece the revolving nosepiece in position for proper use of the microscope during observation. The coarse adjustment knob- The observer the coarse adjustment knob to raise or lower the body tube when the specimen is located at a longer distance to bring the image into clear focus. (Hartley and Gregory, 1964, 21). The fine adjustment knob- The observer uses the fine adjustment knob to raise or lower the body tube through smaller distances during observation to bring the image into a clearer and sharper focus. The diaphragm- This is an aperture regulating the amount of light passing through condenser to illuminate the specimen in a light microscope. Eye-piece- It contains a lens that...
How to use a Microscope

Lenses in a light microscope refract light during observation to make the specimen underneath seem closer (Colgren and Svedberg, 1989, 17). An electron microscope is another example of a microscope. It is also called the scanning electron microscope or the compound and is more powerful than the light microscope. The electron microscope can magnify specimens up to a magnification of five hundred thousand times its original size. Its high revolving power makes it possible for the user to observe objects that are too small beyond the use of a light microscope. This power enables the microscope to separate objects that lie close to each other. The electron microscope does not use light to illuminate it instead uses the negatively charged electrical particles. The electrons form a beam that illuminates the specimens makes the microscope an important research tool in the biology discipline. Electron microscopes that are more powerful magnify specimens up to two million times the size of original objects (Hartley and Gregory, 1964, 33). Stereoscope microscope uses the binoculars that enable the observer to view specimens with larger sizes compared to those observed using both the light and electron microscope. A transmission electron microscope makes use of electrons that pass through the thin specimens during observation.
The user of any microscope may encounter problems in the process of reviewing specimens. Some of these include the image appearing very dark. ...Download file to see next pagesRead More

Scanning Electron Microscope
The signals derived from the interaction between the sample and the electron reveals information regarding the sample inclusive of texture, material orientation in the sample, crystalline structure, and chemical composition. During most of its applications, data collected over the selected sample surface area is generated as a 2-D image which displays the spatial variations of the properties being investigated.

Uses of Electron Microscope
This essay analyzes that in an electron microscope, the electrons are accelerated in a vacuum until their wavelength is shortened. Shorter wavelengths can be produced by increasing the voltage. Beams of these fast-moving electrons are focused on an object. The object either absorbs these beams and forms an image on an electron-sensitive photographic plate.
