Autofocus explained
Draft outline
Scaffold. Replace the bullet prompts with your own text and delete this banner when done.
Image-based autofocus
- How a sharpness metric over a Z-sweep finds best focus; strengths/weaknesses.
Hardware-based autofocus / focus lock
- A dedicated sensor holding focus continuously; when it wins.
- Cross-link: focus-lock add-on.
Choosing between them (and focus maps)
- Comparison: speed, robustness, sample type, data cost.
TODO
Notion sources: TASK-FR025 autofocus settings, TASK-FR027 autofocus not stable.
The focus-lock add-on page already has a calibration plot and simulation GIF to reuse.
