Parfocality: More Comfort and Convenience for Your Work
All Leica stereomicroscopes are parfocally
matched, meaning that you can view a focused
specimen from the lowest to the highest
magnification without having to refocus. The
focus needs to be readjusted only if you want
to view a specimen detail that is located higher
or lower.
Requirements for parfocal work
★ If you are using an eyepiece with dioptric
correction, the procedure differs from this
description. For more information, refer to
page 43
Parfocality
1. Enlarge the view to the maximum level.
2. Focus on the specimen.
You are done! Even if you select a smaller work-
ing distance, the specimen remains pin-sharp.
The parfocality is maintained until you focus on
another level of the specimen.
