Supports the microscope and rests on the workbench.
Supports the objective lens tube and the ocular lens tube; used to carry the microscope.
Moves the stage or the objective lens tube up and down quickly for rough focusing.
Allows slow and precise focusing by moving the stage or objective lens tube slightly.
Magnifies the image formed by the objective lens; usually 10x magnification.
Produces the primary magnified image; usually has multiple lenses with different magnifications.
Supports the slide being observed; has a hole to allow light to pass through.
Hold the slide firmly in place on the stage.
Controls the amount of light passing through the stage opening.
Provides light that passes through the specimen for viewing.
Holds the objective lenses and allows switching between them by rotating.
Place the microscope on a flat surface and plug it in if it has a light source.
Turn on the light source and adjust the diaphragm to control light intensity.
Place the slide on the stage and secure it with stage clips.
Start focusing with the lowest power objective lens using the coarse focus knob.
Use the fine focus knob to sharpen the image.
Switch to higher power objectives if needed and refocus using the fine focus knob.
Total magnification = \(\text{ocular lens magnification} \times \text{objective lens magnification}\)
