Measured 50mm bar (mm)

Apply this correction to analysis

Inkjet printers are recommended and supported. Laser printers are not supported (halftone/screening + scaling behaviour can break fine stripe analysis). Print at 100% scale (no “fit to page”). Measure the 50mm bar — it must be exactly 50mm.

1) Upload photo

Photo tips: place lens over the ladder, slide until the stripes “lock” sharply, shoot square-on, avoid glare.

2) Calibrate + Analyze

Lens ID (optional)

Step A: Click the two ends of the printed 50mm bar in the photo.
