![]() ![]() ![]() It magnifies the size of the object by a complex system of lens arrangement. You will find many different types of microscopes today, that help in different fields of life sciences.A compound microscope is the most commonly used microscope. Antony van Leeuwenhoek would have never imagined that one day, it would be possible to view the minute details of the cell organelles of what he called ‘animalcules’. The microscope has come a long way since the experimental tubes made by two Dutch spectacle makers, Zacharias Janssen and his son Hans in 1590. This helps in illuminating the specimen kept on stage. This is used to help in regulating the amount of light and contrast. The condenser helps in focusing the light on the specimen. ![]() The stage helps in supporting the specimen and helps you keep the specimen on the correct location. These are used for a detailed view of the specimen and small specimens. The low power objective helps in viewing large specimens. The specimen can be easily observed under high or low magnification with the adjustment using fine adjust knob. This helps in switching from one objective lens to the other. The knob helps move the objective lens up and down till the magnified image is seen clearly. This knob helps in focusing the specimen by adjusting the distance of the objective lens to the slide. The eyepiece helps you look at the magnified image of the specimen that is usually magnified by 10x or 15x. The various functions of compound microscope are as follows: Without the microscope, one will never be able to understand the world of microorganisms. In order to help the condenser move up and down and control the lighting focus on the specimen, a condenser focus knob is used. The diaphragm is located above the condenser and below the stage. ![]() This part helps in controlling the amount of light that reaches the specimen. It is usually connected to the iris diaphragm. The condenser is present at the base of the stage. They have a continuous variable light control part at the base that helps in focusing in different light range. Many light microscopes use low voltage halogen bulbs. This helps in illuminating the sample on the slide. The mirror reflects the light from the outside source through the bottom of the stage. The light source that is located at the base of the microscope. The tiny hole in the stage that helps in transmitting base light to the stage. ![]()
