Non-contact 3D surface characterization
The characterization of precision-manufactured and functional surfaces requires measurement technology that is reliable, fast and precise. TopMap are innovative, high-precision and non-contact optical measurement systems that measure on rough, smooth and stepped surfaces. Topmap white-light interferometers are established optical quality inspection tools for laboratory, for production environments or in-line.
Whether form parameters and step-height with large FOV, or roughness and texture with sub-nm resolution - on precision mechanics, optics or microstructures - TopMap optical surface metrology measures it!
Form, steps, roughness, optics or microstructures - measure it!
Surface texture
The surface texture or finish defines a workpiece topography regarding its roughness, waviness, and lay parameters. The particular 3D texturing of a precision surface affects its appearance, friction, corrosion resistance and more. Regarding ISO 4287, ISO 25178 or the new 3-part ISO 21920 - TopMap surface profilers acquire millions of data points for areal evaluation within just seconds.
Surface roughness
Surface roughness measurement with TopMap white-light interferometers provides millions of data points wihtin seconds, enabling repeatable and reliable roughness analysis. Ra, Rz... vs Sa Sz? Polytec offers 3D roughness profilers, both areal and line profilometry for roughness evaluation according to ISO 25178-1, -2, -3 and ISO 4287, 4288 and ISO 3274 and more. Send your sample for a free feasibility study and test how fast the areal and optical roughness analysis works.
TopMap Micro.View(+)
Micro.View® and its big brother Micro.View®+ are the next generation optical surface profilers. Focus Finder and Focus Tracker greatly enhance the ease of use. CST Continuous Scanning Technology turns 100mm travel range into full measurement range. Distinguish and document defects reliably with the Color Information mode. Quantify surface topography with sub-nm resolution and reliably characterize precision mechanics, sealing surfaces, MEMS or microstructures with excellent vertical resolution independent of the magnification.
Surface step-height
Measure step-height on precision surfaces for quality control of functional workpiece surfaces. Characterize step-height in 3D in a non-contact way with optical surface profilers. How to calculate step-height? Differences between profile- or line-based and areal-based step height measurement.
FTP Flatness thickness parallelism
The new Polytec FTP Flatness, Thickness and Parallelism measuring module represents the fast and comprehensive measurement solution for evaluating flatness, thickness and parallelism at once. The FTP measuring module for back and front measurements can become a game-changer in quality control of precision mechanics such as in the watch-making industry, for sealing surfaces, shim rings or optical components and more.
TopMap Pro.Surf+
The all-in-one 3D optical surface profiler from Polytec. The precision of a white-light interferometer, complemented by chromatic confocal sensors to overcome form deviations and any roughness determined with one device. Pro.Surf+ measures topography over a large area and, in so doing, characterizes structures with nanometer resolution.

"Polytec provides excellent support in the development of stable measurement systems and standardized measurement processes."
"With its high resolution, telecentric optics and high measurement speed, the white-light interferometer captures all details. Within a few seconds, it collects two million measurement points on an area 44 x 33 mm² without the need for stitching. The large field of view allows for measuring the entire chip at once. With the cartridge being transparent, we also obtain measurements from top and bottom simultaneously, indicating the exact thickness of the cartridge." Raimund Rother, RnD Engineer from Hahn-Schickard
