Uncovering What There Is To Know About A Compound Light Microscope
Research facilities nowadays include microscopy as an essential tool in scientific studies. Major discoveries in biology, medicine, geology and other researches are mainly based on the advances of using microscopes. The light compound microscope is widely used in the fields of scientific investigations. It is the oldest and simplest microscope but is still broadly used. It uses light to magnify small objects invisible to the naked eye. Light and lenses are used to magnify the object’s image.
The first light microscope was invented around 1950 by Dutch Zaccharias Janssen with his son, Hans. They were both spectacle makers and discovered that using various lenses in a tube enlarged objects. It was then Galilieo Galilei who made a first attempt to create a focusing device. From then on, the rise of the light microscopes started were rapidly needed and used. Several well-known inventors and scientists had contributed to the development of today’s light compound microscope. These people include Anton van Leeuwenhoek who became the father of microscopy. He became famous for his discoveries related to biology. He used lenses to view a variety of very small things. Robert Hooke also became the English father of microscopy who later agreed to Leeuwenhoek’s discoveries and theories on the existence of miniature living organisms thriving in drops of water. He also developed and expanded Leeuwenhoek’s design on the microscope.
Parts of a compound light microscope
Basically, there are twelve parts of a compound light microscope. The eyepiece lens is the lens located at the topmost part of the microscope. It is where you have to look through in order to get an enlarged view of the studied object. It is the first step in the magnifying system. The tube is then the connector of the eyepiece lens to the different objective lenses. The arm is another part that holds the tube and the base. The base supports the whole microscope. An illuminator instead of the typical mirror is used as a source of light. The stage with clips is the flat platform that holds the slides. The part that supports the objective lenses is called the turret and can be sufficiently rotated to adjust the power. There are at least three or four objective lenses in a light compound microscope. The shortest of the lens has the smallest power while the longest has the largest. The rack stop is another part that will allow if an adjustment to get closer to the slide is still possible. The condenser lens lets the light focus to the object being observed. And the last part, called the diaphragm or iris contains holes that will specifically adjust the size and intensity of the light being projected upward.
Proper ways on how to use a light compound microscope
Setting the light compound microscope on a flat top of a table or any other flat surface should be the first consideration. The microscope’s power cord should be plugged in a safe outlet. The light source should be switched on in a largest diameter so that the greatest amount of light will pass through. Rotating the turret at its lowest level will also help get a wide view of the object. Once everything is prepared, the microscope slide containing the specimen shall be clipped on the stage to avoid movements and adjust it until the specimen is properly positioned just below the objective lens. The diaphragm should also be adjusted to receive better light source. View every part of the studied object at a low power and increase its power when focusing on the part you want to observe, to refocus the object cautiously, the turret should be rotated until clear magnification is achieved. When done with the experiment, the slides should be cleaned and the microscope shall be kept in a safe place.
Facts on how a light compound microscope works
The light compound microscope plainly uses the technique on magnification. It purely functions to make objects seem bigger. The resolving power is an ability of the microscope that helps get the view to the more pronounced details of very tiny objects. It is the least distance of two objects which can be distinctly distinguished separately. It is also a task of the wavelength of light used. Generally, a high resolution means a short wavelength of the source of light.
The rapid boost of light compound microscopes in the market signifies how important they are in today’s modernized world. There have been more advances to develop these microscopes through the use of the latest technology and computerization. Someday, scientists could discover and explore more living and non-living organisms we couldn’t have imagined to exist.
