Scanned with the MICROscanR - a 3D focus-stacking robot: www.microscanr.com
Specimen
_____________________________________
- Size: approx. 16 x 8 x 36 mm (the box drawn around it before the scan).
Capture
_____________________________________
- Camera: Sony A7R5 camera (61 Mp) - 1/100 sec. - f11 - ISO 100 - JPG.
- Lens: Laowa 90 mm 1-2 x Macro at ~ 0.7 x (field of view approx. 60 x 40 mm)
- Focus step: 0.6 mm between frames.
Scan
_____________________________________
- Scanned with: MICROscanR
- 480 viewpoints (distributed along a spherical scan shape)
- 10 rings of 48 viewpoints (every 7.5° around), from 54° above to 43° below the horizon.
- Average stack-depth per VP: 38 frames, ranging from 15-60 (measured automatically at 70 viewpoints, interpolated between them).
- 18.385 (77 GB) pictures in total.
- Scan time of specimen (unattended): 4h02m (+ 21 min for the calibration scan).
- Scan date: 21-10-2026.
Splat
______________________________________
- Total splats: 5.0 million
- Start point cloud: 855.881 points
- image resolution used: 7000x4666
- Software: LichtFeld Studio
Lighting
______________________________________
- Lights: Object in diffuse light field between 2x side-beam round (28 cm) LED panels, 2 x 24 Watt

Post processing
______________________________________
- Completely scripted using Helicon and Reality Scan (CLI) as external software
- All steps progress-monitored in web based UI.
- Camera poses were transferred from a scan of a calibration object, taken from the exact same VPs without focus stacking.
- Total post-processing time: ~2h15m (of which focus stacking 40 min).
