Keep a big scan in focus with a focus map
Draft outline
Scaffold. Replace the bullet prompts with your own text and delete this banner when done.
Learning-oriented, for users. Over a large sample the focus drifts because the slide or plate is never perfectly flat. A focus map samples the focus at a few points and interpolates the correct Z everywhere in between — so a big scan stays sharp without running a full Z-stack at every tile.
The idea
- Sample tilt/curvature across a large area; interpolate a focus surface.
TODO
This Focus Mapping video was previously on the Day-n guides page; it lives here now as the tutorial. Decide whether to keep the video, replace with screenshots, or both.
Step 1 — Place focus points
- How to add focus reference points across the region and focus each one.

Step 2 — Run the mapped scan
- Start the scan using the interpolated focus; how it differs from single-Z.
When to use focus map vs. autofocus vs. Z-stack
- Comparison table prompt: speed, robustness, data size, sample type.
