Why Polytec for optical surface metrology
Polytec has decades of experience in surface metrology and designing white-light interferometers. Our Polytec optical profilers combine advanced white-light interferometry with robust optical design to deliver reliable 3D surface data—in the lab and on the shop floor. You benefit from:
Optical profilometers designed for real applications — from microscope-based systems for microscale structures to telecentric solutions for large-area form measurement
Proven measurement expertise through feasibility studies and contract measurements on customer samples
Reliable results beyond the lab, supported by robust system design, environmental compensation, and automation-ready concepts
Global service and long-term partnership, including training, customization, modernization, and a four-year warranty
Flexible access models, from demos and feasibility checks to rental, leasing, and measurement-as-a-service via PolyFlex

Surface metrology system: From microscope-based to telecentric optical designs
Choose the profiler type that matches your scale, workflow, and precision requirements. Whether you work on micro-features or large mechanical components, Polytec offers the right optical technology for reliable 3D topography.

Micro Profiler
Micro.View profiler systems are optimized for measurements with sub-nanometer resolution. With focused optics and high vertical resolution they enable detailed analysis of microstructures, surface finish and material distribution where even the smallest deviations matter.

Macro Profiler
Pro.Surf inspects flatness, step height and parallelism on large parts and multi-part trays — non-contact, in seconds. No-crash telecentric optics measure even into bores, with the precision and repeatability production demands.

Metro.Lab
Metro.Lab is a compact, wide-area surface profiler. It combines high measurement performance with a small footprint—ideal for space or budget conscious applications that still require reliable 3D surface data.
Not sure which profiler fits your task? Two guides to help you decide.
Two short guides take you through the key decisions: one helps you choose the right measuring technology, the other the right measurement scale — micro or macro. And with our try-before-buy offer, you get the practical way to confirm your choice on your own parts.

Operate your metrology task—easy, precise, repeatable
Optical surface metrology covers a wide range of functional parameters—from roughness and texture to flatness, step height, thickness, and tribology. Explore some metrology jobs below, conducted by our customers and in our application labs as contract measurements.
