Parfocality: More Comfort and Convenience for Your Work
All Leica stereo microscopes 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 only be readjusted if you want to
see a specimen location that is located higher
or lower.
Requirements for parfocal work
O If you are using an eyepiece with dioptric
correction, the procedure differs from this
description. For more information, refer to
page79.
O For the procedure for adjusting the parfo-
cality for the objective nosepiece, refer to
page29.
O For the procedure for adjusting the parfo-
cality for the Leica FluoCombi III, refer to
page33.
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.
