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.
