Question

I'm starting with a blurry image. When I click the auto-focus button to automatically focus the objective the image gets better, but is still blurry. If I click auto-focus again, the image gets even better.

Is there something I can change to improve the auto-focus operation?

Answer

Yes. There are several auto-focus parameters you can change to suit your needs.

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

Note
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.
