Service & support that keeps your metrology running

Your metrology results only matter if your system performs reliably every day. Polytec supports you throughout the entire lifecycle — from first feasibility checks to long-term maintenance, upgrades, and flexible access to systems via PolyFlex.

  • Feasibility & consulting to define the right setup before you invest
  • Contract metrology (PolyMeasure) for fast expert results
  • Commissioning, training & enablement for a smooth, confident start
  • Calibration, maintenance & repair to ensure long-term accuracy
  • Modernization & upgrades to keep your system future-ready
  • PolyFlex options (rent, lease, measure-as-a-service) for maximum flexibility

Choose the right surface profiler with confidence—let us run a feasibility study with your sample.

Deepen your know-how in optical surface metrology

Explore practical guides, standards explanations, and technology insights that help you understand, compare, and apply optical surface metrology — whether you’re evaluating systems or improving your process.

Discuss your demands with our experts

Let’s start with a short discussion about your parts, tolerances, and workflow — and, if useful, we can add a feasibility study, PolyMeasure (contract measurements), or a PolyRent trial as optional next steps.
