MicroscopySummaryThe whole exercise consisted of maintaining and using the microscope. We carried out various activities which allowed us to become familiar with the parts and uses of the microscope. Using the microscope, we observed different objects such as cotton, silk, hair and even a letter “e”. We visualized it using both the low power lens and the high power lens. We carried out these activities in order to better understand how the compound optical microscope works and also to know the different procedures for setting up a slide. The results of the activity allowed us to learn how to use the microscope effectively. I discovered that the iris diaphragm controls light and uses LPO and HPO. I also noticed that the view of the illuminated object is inverted.AbbreviationsLPO- Low Power LensHPO- High Power LensIntroductionThere are many things that are not visible to the naked eye. What most of us don't realize is that there is a world full of wonders; A world full of diversity and “magic”. A world called microscopy. It's amazing how a single device called a microscope can allow us to observe objects too small for the human eye. A microscope has the power to magnify an object from 100x to 1,000x or more. In fact, there are many microscopes, each with their own capabilities. Examples are the atomic force microscope, the scanning probe microscope and the electron microscope. Microscopy is the technique by which a person is able to view images of structures too small for the naked eye. In optical microscopy, light is reflected through a series of lenses that ultimately illuminate the object being viewed. The objectives of the exercise...... middle of paper ...... and the different parts and uses of the microscope. I conclude that compound light microscopes give inverted images of the object because of the reflected light; and that the passage of this light is controlled by the iris diaphragm. I also conclude that every part of the microscope is important for its correct and efficient operation.
