Pro.Surf+: Macro optical profiler with roughness sensor

Pro.Surf – large area optical profiler for quality control

Fast and reliable non-contact inspection of flatness, form, and step heights — optimized for large parts and multi-sample trays.

Designed for fast form and flatness inspection on large area components

The Pro.Surf is a macro (large-area) optical profiler with telecenctric optics, optimized for form and flatness inspection over wide fields of view — where microscopic systems reach their limits. It supports fast, non-contact inspection of:

  • flatness & form 
  •  trays & batch parts 
  • bores & recesses 
  • in production & QC environments

Its large single-shot field of view, 70 mm vertical measuring range, and True Stitching capability enable efficient and accurate flatness, shape, and step-height measurements with minimal setup effort.

Features

Embedded features support high precision and efficient workflows - even in rough environment

Get a wide FoV up to 44 × 33 mm (extendable to ~230 × 220 mm via stitching), automation-ready operation with motorized stages, recipe control and barcode start, plus telecentric WLI/CSI and a 70 mm Z-range for nanometer-level vertical performance.

WLI with telecentric optical design

→ Keeps geometry accurate across height and dept

Traceably calibrated WLI/CSI delivers non-contact, areal 3D data with nanometer vertical resolution. The telecentric optical approach keeps the beams / rays parallel to the optical axis, preserving constant magnification and uniform illumination over height—even enabling measurements in holes.

  • Non-contact, repeatable, fast areal scans
  • Phase/envelope evaluation for smooth and rough surfaces
  • Smart surface/adaptive scanning for varying reflectivities
  • Long-life 525 nm LED
True Stitching - Higher accuracy for wider samples

→ True Stitching provides unmatched precision when scanning wide-area samples

Because larger surfaces exceed the single-shot field of view — stitching merges tiles into one accurate dataset. The metrology quality of such large-area measurements depends on the optics and sensing technology, the number of tiles and the stitching algorithms. 

True Stitching delivers high-fidelity large-area measurements by minimizing stitching artifacts and preserving geometry.

An independent benchmarking at a leading German technical university compared six optical profilers from different manufacturers and the Polytec profilometer demonstrated the highest stitching and measurement quality. This is achieved through several key features:

  • Large single-shot FoV → fewer tiles and seams, less cumulative error
  • Sophisticated stitching algorithms → controlled overlap, robust registration, and metrology-safe blending that preserves steps and edges
  • For Pro.Surf: Telecentric/CSI optics with correlogram evaluation → stable geometry and height fidelity across tiles

The result is high-fidelity, large-area topography with fewer artifacts and audit-ready residuals—what we call True Stitching.

Large field-of-view (FoV) optics

→ Reduces stitching and cycle time

Pro.Surf offers a wide single-shot field of view up to 44.9 × 33.8 mm (with ~1.91 million points), so broader samples or multiple parts can be measured in a single acquisition. With the built-in stitching function, coverage extends up to ~228 × 221 mm.

  • Measure multiple samples at once; automatic sample recognition available
  • Short cycle times; reduced stitching effort
ECT – environmental compensation technology

→ Stabilizes results in real shopfloor environments

Noise, vibration, and temperature fluctuations can affect measurements. ECT compensates for such disturbances and ensures consistent data — even on the shop floor.

  • Improves reliability in noisy or unstable environments
  • Enables automation and inline QC without full isolation
  • Especially helpful for sensitive components (e.g., MEMS, thin films)
Ready for automated metrology workflows

→ Enables unattended, repeatable measurements

The modular design and motorization options makes it easy to automate and integrate the Pro.Surf profilometer into existing process and machines. A bundle of features and capabilities enables highly efficient and unattended metrology workflows:

  • Pattern matching and Smart Scanning Technologies
  • Motorized X, Y, Z, tip/tilt stages
  • Large FoV and automated stitching for high-resolution scans over large areas
  • Recipe system in TMS (Software) for operator-independent workflows
  • Rugged design without moving parts and ECT (environmental compensation technology)
Pattern matching 

Machine-vision routine that finds and registers parts against a template so recipes hit the right locations (even if parts are shifted or rotated). Ideal for trays and multi-sample runs; pairs well with automatic sample recognition to reduce fixturing. 

Smart Scanning Technology

Acquisition mode that adapts to varying reflectivity/contrast so you can measure “almost any surface” reliably in one setup; included in the TopMap software.

Feasibility check?

Send us your sample and we run a feasibility study with our profiler and walk with your through the results. 

This gives you a precise understanding of the optical profiler’s performance on your actual samples.

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.
