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 magni-
fication without having to refocus. There is no
need to readjust the focus to view of specimen
location 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 61.
For the procedure for adjusting the parfo- ★
cality for the objective revolver, refer to
page 26.
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.
