SXM Viewer

SXM Viewer is a scientific SPM (Scanning Probe Microscopy) data analysis tool tuned for data acquired with an Anfatec SXM controller running an Omicron Infinity microscope (tribus head, QPlus sensors at 8.6 K). It also supports Nanonis .sxm files via a conversion adapter.

Main menu overview

What it does

  • Browse large SPM data folders quickly via a thumbnail grid and minimap — no blocking on full renders.
  • Analyse images with profiles, angle measurements, cropping, filters, drift correction, and A/B comparison.
  • Visualise spectroscopy — single traces, matrix scans, waterfall plots, and parabola/KPFM fits — alongside your scan images.
  • Overlay 3D and 2D molecular models, scale bars, and acquisition metadata directly on images.
  • Export publication-ready figures to PNG, SVG, PDF, and PowerPoint, animations from a scan sequence, or compose multi-image figure layouts in the built-in canvas.
  • Save sessions (with autosave/recovery) and collections so you can return exactly where you left off, or curate a cross-folder set of key images.

python -m sxm_viewer

If you prefer the project-managed installer instead of Conda, see Installation. That page also explains the Windows launcher scripts and the supported Python versions.
