Stereo Microscope Diagram
There are generally two types of microscopes: stereo and compound microscopes. Stereo microscopes are low-powered in comparison and can enhance objects 10-40X. It is a great microscope for looking at rocks, insects and flowers, while compound microscopes are better for seeing very small things on prepared slides.
Instructions
1. Plug in your microscope and set it on a flat surface where it will not move around. Make sure the space you have available is large enough to work on.
2. Turn on the lighting source for your microscope. Anything on a slide should be lit fron underneath, while solid or opaque objects should be lit from above.
3. Place your specimen on the stage plate. Use the clips if it is flat or if you can fold the edges down to fit under the clip.
4. Turn the eyepieces slowly while looking into them in order to focus them. You will know they are focused correctly for you when you can look through them without straining your eyes.
5. Set the magnification level (5X, 10X, 40X, etc.) you want by turning the objective turret. Make sure the magnification level mark on the outside of this faces the front of the microscope.
6. Turn the focus knob until the object you are looking at comes in clearly. The focus knob takes into consideration magnification, while the eyepieces only are turned to adjust to your eyes.
