How to Use a Microscope
Follow these step-by-step instructions to ensure you get your microscope working in no time at all:
First of all, you need to make sure that the microscope is on a flat surface, such as a table, so that it can stand up correctly without the slides or whatever you may be observing on the mechanical stage falling out of place.
Depending on the microscope you own, you may need to connect your microscope to an electric source in order to use LED lights so you can actually see what is on your slides. However, some microscopes use mirrors to reflect natural light, so that an electric outlet isn’t necessary. Once you have the light on, you need to adjust the diaphragm control to the largest hole to let the most amount of light in.
Now, you need to adjust the nosepiece so that you have the lowest objective lens selected, usually 40x works great at first because it allows a large field of view. This means you will be able to view the majority of your sample and zoom into the parts of interest accordingly.
Once all this has been done, you are ready to insert your slide. For beginners, its best to use a prepared slide, one that already contains an prepared specimen, because preparing a slide by yourself can be difficult. However, if you do have your own slide prepared, this too can be put onto the mechanical stage, after this observe your objective lens and stage from the side and adjust the coarse focus knob so that the objective lens is just above your slide.
Be very careful as glass slides in particular are very easily broken.
Adjusting the coarse focus knob, will make the objective lens go up, away from the slide, do this until the specimen becomes clearer. You can then use the fine focus knob for fine tuning the focus.
To really sharpen the viewing, adjust the diaphragm to allow the correct light onto the specimen. This will ensure the specimen has sharp contrast and give you a better viewing experience.
You can move the microscope slide around the stage to ensure the area of interest is in the field of view and adjust the diaphragm accordingly to achieve the best image.
Now you an adjust the objective lens as needed, and use the fine focusing knob for focusing adjustment. Repeat with the 40x objective for 400x magnification, which will enable you to see even more detail.
