Ultra precision machining
Measure UP machined parts with highest precision, measurement speed and repeatability: Form accuracy measurement in the µm range, and roughness measurement resolved in the (sub)nanometer range - for inspecting precision mechanics in ultra precision machining, analyzing UP surfaces in both form and finish from rough to optically smooth materials.
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.
TopMap Pro.Surf+
The multi-sensor profilometry system measures areal topography and form on an exceptionally large field-of-view (up to 230x220 mm) like common for Pro.Surf – while adding the chromatic-confocal sensor for complementary roughness line profile evaluation. Fast scanning, repeatable measurements for combined form & roughness characterization resolved in the nm range.
Glass & transparent materials
Secure quality and functionality of optics, optical and transparent components like lenses, mirrors, freeforms, optical elements and optics equipment by optical measurement of surface form and surface roughness down to the sub-nanomer level with Polytec optical surface profilers.
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.
TopMap Micro.View
TopMap Micro.View® is an easy to use optical profiler in a compact table-top setup. Choose Micro.View® as the cost-effective inspection tool for examining precision-engineered surfaces down to the sub-nm range, for inspecting roughness, microstructures and more surface details. Custom objectives 0.6x to 111x and stage options allow for application-specific finetuning.
Measure 3D form, flatness or roughness? On glass, metal or dull ceramics?
Faster surface characterization - more reliable and efficient in 3D
For characterizing precision-manufactured and functional or sophisticated surfaces in detail and 3D, it requires measurement technology that is reliable, fast and precise. Guaranteeing functionality and detecting defects at an early stage avoids unnecessary cost and increases the overall product quality and lifetime. TopMap from Polytec addresses surface metrology applications with innovative, high-precision, non-contact optical technology that works on rough, smooth and stepped surfaces. White-light interferometers of the TopMap sensor family are established optical quality inspection tools for the controls laboratory, in 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!
