Condenser: Situated below the diaphragm, the condenser controls the focus of the light passing through the specimen. By manipulating the position of the condenser, scientists can adjust the illumination and enhance the contrast of the image.
-
Reflector: Positioned above the base of the microscope, the reflector consists of a plane mirror and a concave mirror. The plane mirror reflects light from an external source, such as a lamp or natural light, while the concave mirror concentrates and directs the light towards the specimen.
-
Objective Lenses: Located above the nosepiece, the objective lenses come in various forms, such as low power, high power, and oil immersion lenses. These lenses provide different levels of magnification, allowing scientists to choose the optimal lens for their specific research needs.
-
Ocular Lens: Also known as the eyepiece, the ocular lens is where we observe the magnified image of the specimen. By combining the magnification of the objective lens with the magnification of the ocular lens, the compound microscope delivers a detailed and enlarged view.
-
Diaphragm: Positioned below the stage, the diaphragm controls the intensity of light that passes through the specimen. By adjusting the diaphragm, researchers can manipulate the brightness and contrast of the image, optimizing the visibility of the microscopic details.

How to Effectively Use a Compound Microscope
[youtube v=”uEgM3gk8n6k”]
A compound microscope is an essential tool used in various fields such as biological research, medicine, material science, nanotechnology, and education. With its ability to magnify tiny objects on a slide, it allows us to study cells, tissues, microorganisms, diagnose diseases, visualize nanoscale objects, and facilitate hands-on learning experiences. This article will guide you on how to use a compound microscope effectively.
Understanding the Key Components
To effectively operate a compound microscope, it’s essential to familiarize yourself with its key components. These include:
-
Condenser and Reflector: The condenser controls the focus of light passing through the specimen, while the reflector reflects and directs light onto the specimen.
-
Objective Lenses: The compound microscope contains multiple objective lenses that provide different levels of magnification. These lenses include the scanning objective (5X), the 10X objective, the 40X objective, and the 100X objective.
-
Ocular Lens: The ocular lens is where the magnified image is observed.
-
Diaphragm: The diaphragm controls the intensity of light passing through the specimen.
Step-by-Step Guide to Using a Compound Microscope
-
Setting Up the Microscope: Start by plugging in the microscope and turning on the illuminator. Use the rheostat to raise the level of light, starting with it open halfway. This will ensure proper illumination for your specimen.
-
Preparing the Slide: Use the course focusing knob to lower the stage to its lowest position. Open the clip and place your slide on the stage, then release the arm. Use the stage adjustment knobs to move your specimen over the condenser, ensuring it is centered and in the light.
-
Rotating the Objectives: Grip the turret to rotate the objectives without pulling or pushing on them. Begin with the lowest power objective, also known as the scanning objective (5X). Rotate the turret until the lowest power objective is above the specimen and it clicks into place.
-
Focusing and Centering the Specimen: Look through the oculars and use the course focusing knob to slowly raise the stage until your specimen comes into focus. Once it’s in focus, use the stage adjustment knobs to center your specimen in the field of view.
-
Switching to Higher Magnification: Rotate the turret to switch to the next highest magnification objective. From this point on, use only the fine focus knob for focusing. Refocus the specimen and recenter it in your field of view using the stage adjustment knobs.
-
Using Immersion Oil: If you need to use the highest magnification objective (100X), place a drop of immersion oil on top of the slide, just above the light source. Move the 100X objective into place without using the immersion oil on the 40X objective, as it may damage it. Refocus and recenter the specimen using the fine focus knob.
-
Completing the Observation: After viewing the specimen, lower the stage all the way down. Remove the slide and clean off the immersion oil from both the 100X objective and the slide. Finally, move the lowest power objective (10X) into place above the light source, preparing the microscope for the next observation.
Remember, using a compound microscope requires careful handling and attention to detail. By following these steps, you can effectively observe and study various specimens, contributing to advancements in research, healthcare, and education.
