TopMap surface profilers
Polytec offers complete optical surface metrology solutions for quality inspections of engineered surfaces and form evaluation – whether flatness or step-height on CNC-machined precision parts, warpage and form on smooth optics, or texture, finish or MEMS and microstructure analysis.
We build the most reliable white-light interferometers, backed by application service and know-how, 4 years of warranty and a lifetime free software updates.
Our profilers measure non-contact and promise precise and repeatable measurements. Benefit from the extraordinary large vertical range and high Z resolution, and the impressive Field-of-View (FOV) even allowing multi-sample measurements. Whether fast scanning of large samples or thorough texture and roughness analysis with sub-nm resolution– challenge the TopMap profilers and test for free!
Large FOV 33x44mm, 100mm Z range, configure your surface profiler!


Optical profilers VS tactile stylus profilers
Feature & benefit | Optical profiler | Tactile profiler (stylus) |
Method | non-contact, non-destructive, repeatable results | influencing workpieces, abrasive, varying significance of data |
Affordability by all users | limited | most |
Highly sensitive surfaces | ideal | not suited |
Varying optical surface properties (reflectivity) | little sensitive | no limits |
Visualization of sample | intuitve, meaningful 3D data (WLI) | simple profile line |
Data collection per time | high density on XYZ | low |
