What Are The 10 Steps in Using A Microscope? 

Using a microscope can be easier than most people imagine. But it requires some basic techniques for safe use and to obtain clear images. The steps below will guide you through the entire process of using a microscope from start to finish:

STEP 1: Set the Microscope 

Setting the microscope should be the first step before attempting to use it. Start by placing it on a table at a comfortable height. It is best to locate it near a power source. 

Next, connect the microscope to a suitable energy source but don’t turn it on until it is ready for use. However, you might skip this step if your microscope uses a mirror in place of an illuminator. Then, all you need to do is find an area where you can access natural light.

STEP 2: Set the Eyepiece and Nosepiece 

Start to adjust the nosepiece of your microscope. Revolve it gently until it reaches the perfect position of its lowest objective lens. The lowest objective lens is usually 4x position for most microscopes. 

Rotate the left eyepiece gently until the diopter ring marks align with the line on the tube. You can note this when the eyepiece makes a click sound. But not all types of microscopes give a click a signal.

STEP 3: Mount Your Specimen 

Your specimen is what you intend to observe under the microscope. Mounting it means placing it on the stage where you will view it. Ensure that your slide is clean to avoid interference and contamination of your specimen. 

Be sure that other accessories like the ocular lens and glass for the lamp housing should be clean. Further, protect your specimen by gently placing the coverslip on it. Also, ensure that the coverslip is clean as well. 

Step 4: Set the Stage 

After mounting the specimen, ensure that the stage is appropriately set. Position the sample at the center of the stage. Use the metal clips on the microscope to hold the stage in place. Don’t forget it should be under the lowest objective lens. 

STEP 5: Adjust the Condenser 

The condenser helps you to regulate the amount of light. Set the adjustment knob to allow the maximum amount of light. You might not need a high illumination if you are using a low objective. 

So, all you need to do is make suitable adjustments using the diaphragm under the stage. Note that varying the condenser diaphragm will help you to adjust the depth of field and contrast. 

STEP 6: Adjust the Fine and Coarse Adjustment Knob

This step will help you to control the depth and contrast of the field. Look through the eyepiece to set the coarse adjustment knob. Rotate the knob to help you bring the specimen. 

Ensure that the lens and the slide do not come in contact during the adjustment. It is best to use the coarse knob to focus at 10x objective. For the fine adjustment knob, it helps you to bring the image to a fine focus. The fine focus knob will help you get the finest detail of the specimen.

You shouldn’t need to touch the coarse adjustment knob. Instead, position the 40x objective lens before adjusting the fine knob to bring the image to focus. 

STEP 7: Set Your Eyepiece 

It is time to find a perfect position for your eyes to make the observation easy. Start by closing your left eye and use the right eye for image focus. Next, use the fine adjustment knob to bring the image to a perfect focus. 

Then, close the right eye and focus the image on your left eye. You only need the diopter ring to adjust focus on the left eye. Do not alter the coarse and fine adjustment knob. 

STEP 8: Examine the Specimen 

If you get the steps above correctly, move on to examine your specimen. Look through the eyepiece to observe your sample. You should get a clear image if your adjustments are suitable. You can also get a clearer picture by regulating the fine adjustment knob. 

STEP 9: Keep Switching Power 

Once you get your image at the lower objective, you can switch to higher options. From the lowest power, you can increase it to medium power. The change of power will help you to get more details. 

Use the fine adjustment to readjust the focus. Then, when you get your focus, you can readjust the power to the highest option. 

STEP 10: Keep Observing Your Specimen 

For the rest of your session, all you need to adjust is the fine focus knob. You will get used to these steps with regular practices. You can also change the specimen by unmounting the existing one and placing a new one. 

How Do You Use A Digital Microscope? 

Using a digital microscope is slightly different from regular microscopes. But basic knowledge about using a traditional microscope will ease the process here. Do you want to learn how to use this device as well? Find out below!
