When I click the auto-focus button to automatically focus the objective, the image is still blurry. Is there something I can change to improve the auto-focus operation?


Yes. You can change the auto-focus parameters to suit your needs.

  • Refer to Auto-Focus Settings for general information regarding the default auto-focus settings.
  • Change the Coarse Focus Range to 1,000 or 2,000 to increase the depth searched for focus.

Changing the Coarse Focus Range too high can cause the uScope to focus on debris, dust, fingerprints, etc. on the cover slip instead of the specimen.
