Unlock your potential in performance and quality
Our Metro.Lab white light interferometer is a compact optical measurement system that captures areal 3D topography with nanometer-level vertical resolution down to 2.85 nm.
Telecentric optics maintain constant magnification and a safe working distance, so you can measure and into bores without contact. Recipe-driven software supports repeatable QA routines and reporting.

Optical bench profiler for efficient quality inspection
Fast pass fail decision with large FoV
Seize a large single field of view 37 × 28 mm (~1.24 Mpts) for mid- to large sized sampels in a single shot. With extended lateral coverage up to 87 × 78 mm it even allows for multi-sample measurements and quick pass/fail checks. In vertical (Z Axis), the specimen height can range from 0 to 70 mm.

Measuring deep and hard-to-reach surfaces
With the telecentric optics and a large z scan range, Metro.Lab reaches deep holes, bores or recessed areas while keeping a safe gap to the part and thus avoiding collision.
This is particularly helpful on macroscopic components with bores or recesses where conventional optics face shadowing effects.

Accuracy you need with a reproducibility you can trust
A 70 mm vertical measuring range handles large steps and form deviations, while nanometer-scale performance supports tight tolerances: <2.85 nm vertical resolution (phase evaluation).
The rugged design without moving parts demonstrates a low measurement noise and high repeatability. In addition a vibration damping system is integrated to rougher environments.

ISO compliant recipes and documentation
TopMap profilers support recipe-based measurements for recurring inspections and testing routines. Barcode scanners load predefined settings and evluations. The software automatically recognizes lay and form of your sample type avoiding any need for mechanical fixture. Operators start ISO compliant and reproducible measurements with just one click without further training.
Evaluations follow DIN/ISO standards (e.g., ISO 25178, ISO 4287/4288). Results are visualized with clear pass/fail, and reports can be archived or exported to QS-STAT™ for SPC—supporting efficiency, repeatability, and traceability in lab or production.

Metrology tasks and visualizations
Below or some real-life results from standard tasks across common engineering materials. Those examples are gathered by our application centers which does feasibility studies and offers contractual measurement services.

Compact 3D profilometer with wide Field-of-View (FoV)
The Metro.Lab platform combines large-area optics, long Z-range and ISO-aligned software for precise, repeatable measurements — even on recessed or delicate features.
- Broad Field of View (37 × 28 mm with True Stitching 87 × 78 mm) enable batch or large sample analysis
- Telecentric lens enables measurement of bores, holes and recessed areas
- 70 mm large Z range with nm resolution
- Predefined recipes and barcode scanner for routine inspections at production level

Telecentric optics
Captures even recessed areas for measureming in holes without shadowing effects.
Smart Scanning Technology
SST supports measurement of reflective or matte surfaces
Decoupled metrology
Integrated vibration damping for rugged measurements in rougher surroundings.
Large Field-of-View (FoV)
Single measuring field of 37x28 mm. With True Stitching up to 87 x 78 mm.
Sample positioning
Automated pattern recogniction allow multi-sample measurements, stitching expands FoV to 87 x 78 mm.
Flexible vertical range
For specimen heights from 0 to 70 mm
The Metro.Lab capabilities in numbers
| Vertical range | 70mm |
| Vertical resolution | 2.83 nm |
| Field of view (FoV) | 37 x 28 mm |
| FoV with True Stitching | 87 x 78 mm |

Need more speed and FoV? Pro.Surf is your option.
Both Metro.Lab and Pro.Surf are macroscopic, telecentric WLI/CSI profilers with a 70 mm Z measuring range. The Pro.Surf line may be a better choice in case of:
- Bigger samples
- Faster inspections of batches or higher throughput
- Higher resolution and highest repeatability
- Production integration or inline measurements
