Steps for using a compound light microscope
Steps for using a compound light microscope
Always carry microscope with TWO hands. One on the neck and one on the base.
Make sure the STAGE is all the way down and it's on the LOWEST OBJECTIVE LENS (smallest)
Place slide on stage and secure it with stage clips
Use COARSE (large) adjustment knob to bring sample into view. Use FINE (small) adjustment knob to focus.
If you need to, switch objective lenses to get a closer look. To focus at a higher objective, ONLY use the FINE ADJUSTMENT knob!
When you are done with the slide: Lower the stage. Switch to the lowest objective lens. Remove the slide.
Wind the cord and put the cover on the microscope.

From low powered simple microscopes that give us a little bit of detail to high powered electron scanning tunneling microscopes that gives us incredible detail, microscopes have improved our understanding of the microscopic world.
