    Troubleshoot if you're still not seeing your sample. A lot of times your stage clips are loose, or your slide is not directly placed under the light source. Double check your setup and start again.

Tips

  • Make sure you have your light source on high, and your diaphragm completely open.
  • Try practicing on a virtual microscope where you don't have to be quite exact to use it.

Warnings

  • Make sure you use the fine knob first; it can really be a hassle putting it back on focus using the coarse adjustment knob.
