Using the Initial Focus Method

Initial Focus Method

The uScope Navigator Application offers several different focus methods you may use when scanning a region of interest.  This video discusses the Initial Focus Method and how it is best used.

After selecting the region to scan, you are prompted to select an initial focus point.  The Initial Focus Method uses this focus point to capture each field in the scan region.  The objective remains stationary while the stage moves from field to field.

Initial Focus is the fastest focus method.  But, in order for the scanned image to be in focus, the focal point of each field must be within the objective’s depth of field.

In general, this means that Initial Focus is best suited for:

  • Small regions of interest where re-focus is not required from field to field.
  • Specimens that are very thick where something is always in focus.

This makes Initial Focus well-suited for scanning insects.
