Some Important Applications of a Compound Light Microscope

The history of the compound light microscope started way back 1500’s and it is popularly attributed to Zacharias Janssen. This remarkable tool is capable of a thousand times viewing details by the use of light and lenses to enlarge the illustration of the specimen being studied. It contains two lenses, which enable greater magnification. These lenses are the ocular and the objectives lenses. Other important parts of this kind of microscope include the tube, arm, base, illuminator, stage, revolving nosepiece, rack stop, condenser lens, and diaphragm.

The development of the compound light microscope has been skyrocketing as ever. Its applications in various fields have also increasingly improved. One of the applications of this type of microscope falls as complicated as different fields of science down to as simple as sand analysis.

For most hobbyists, sand analysis is one of the fascinating purposes of having a compound light microscope. It is a granular material which is coarser than any other materials, but finer as well. Observing sand samples requires the best variety of microscopes.

On the broader side, a compound light microscope is useful in the field of histology. When scientists study tissues, these tissues are sectioned into thin slices by means of a microtome. As an important tool in histopathology, microscopic studies are performed to accurately diagnose cancer and other related diseases that typically require examination of certain samples. This examination may be done during an autopsy, biopsy, or surgery. In case of animal tissues, they perform necropsy to study the specimens.

Some laboratories make use of compound light microscope to engineer tissues so that they can create a similar tissue that would react to other tissues. This way, they can determine the behavior and interaction of various cells that are infected or exposed to related medical conditions. Histology also employs this kind of microscope for fixation, processing, embedding, sectioning, and staining of tissues. Staining in particular, is a commonly used technique to give contrast to the specimen being examined.

Another field of science which utilizes a compound light microscope is pathology. Diseases are studied and diagnosed through the examination of cells, tissues, bodily fluids, and organs. It has been a difficult task to understand all the mechanism of our body. This is only made possible through this microscope, Scientists were able to outline how our body responses to injuries such as infection, trauma, loss of blood blow, poisoning, and other genetic damage. This resulted to carefully avoiding external factors which could incite or exacerbate the injury. Cellular adaption to any injury is studied as well as its death or even tissue repair.

In cell biology, living cells are studied through intensification of fluorescent images under low illumination. Also with a compound light microscope, contrast images are enhanced to generate a clearer structure of the cells.

It has been also useful in live blood analysis. As an alternative technique, live blood analysis allows viewing of impurities from the blood. Other related blood conditions has been made possible to be viewed with a compound light microscope. Before, this was not possible to do as most of the specimen are too transparent and cannot be achieved with good clarity. At present, staining has been employed to study these types of specimens.

Biotechnology also employs this type of microscope for investigation of organisms in agriculture, medicine, and food science. This field embraces major industrial areas such as nonfood uses of various crops, agriculture and crop production, health care, and environmental purposes. Studies are conducted by way of staining the organisms. The reactions and physiological changes can be easily investigated. This way, useful and harmful bacteria can be determined.

Another application is in the field of microbiology and bacteriology where it has been regarded as a precision instrument for the microbial world. This comprises the ways of identifying bacteria, to classify them, and to characterize them according to species. Under the microscope, bacteria are studied to determine what kind of nutrient are they capable of growing or may be not at all. If it grows, temperature is determined and substances produced are established and used for practical purposes such as waste processing. Bacteria are known to be remarkable in degradation. They are also used to clean up harmful oil spills as they are capable of digesting hydrocarbons. Genetic engineering enabled bacteria to be created to breakdown camphor and xylene.

With the advancement of technology, compound light microscopes are employed with digital means to produce better microscopic images. There are a lot of digital accessories that are adaptable to this type of microscope. This would make work much easier to achieve more accomplishments in the field of microscopy,
