The most affordable 3D surface roughness profiler
Roughness Testers are Micro.View profilers with a predefined configuration — designed as a cost-efficient entry systems. They deliver reliable 3D roughness and texture analysis using the same high-precision sensor head for accurate measurements on matte to highly reflective components.
- ISO-compliant roughness evaluation:
R parameters for profile lines and S parameters for full surface evaluation - Compact table-top design
- Automated XY stage (optional)
- Upgrade guarantee (attractive trade-in options if your need additional automation features)

A solid, high quality profiler to start with optical surface measurement
With the Micro.View roughness tester configurations, you capture classic roughness "line" parameters (Ra, Rz,...) but also real areal data (Sa, Sq,..) — fast, non-contact and repeatable.
And optical profilers have more advantages: Unlike stylus measurements, optical surface profilers capture the complete 3D topography and there is no risk of damaging the surface of the sample.
Many conventional optical profilers struggle with highly reflective, dark, low-contrast, or transparent materials. Micro.View overcomes this using the embedded correlogram and SST smart scanning technologies, which allows multiple scans at different acquisition settings. This enables reliable measurements even on complex materials.
The result: precise 3D data for roughness, microstructures, step heights, and flatness evaluations — even on the most challenging surfaces.
With decades of experience, our engineers combined phase and envelope evaluation of the correlogram with inherently low system noise. This results in sub-nanometer vertical resolution and outstanding 3D data clarity.
This level of precision empowers engineers to verify tight tolerances, optimize production, and ensure long-term reliability.
When to move from tactile to optical tester?
For decades stylus instruments measure a single line in an efficient way to quickly inspect R profile parameters. Modern optical profilers evaluate entire areas as requested by customers and modern standards like ISO 25178.
We see multiple customers stepping up to measure optically the surface properties. The major reasons for that shift are:
- Measure sensitive or soft surfaces without damage
- Capture full surface texture instead of single traces
- Detect functional issues earlier and more reliably
- Save time through faster area measurement
- Compliance to newer industrial standards
Who is the roughness tester for?
- Quality control labs who have to comply with the latest standards
- High quality manufacturing need precise surface finishing and processes
- Universities & teaching labs
- R&D departments who need in-depth surface insights
(e.g. tribology, etc.)
Polytec Roughness Tester configurations
With 100 mm Z measurement range and the CST Continuous Scanning Technology, the Roughness Tester measures complex topographies at sub-nm resolution. This convenient table-top setup features integrated electronics and is easy to commission and operate.
The Roughness Tester is delivered in a predefined configuration to offer maximum performance at an optimized entry price. Both roughness tester configurations offer all functionality needed for typical roughness evaluations:
- Sensor head with sub-nm resolution capability and 5-port objective turret
- Compact base stand with integrated vibration isolation
- 10x objective (more objectives optionally available)
- Software for roughness evaluations according to industry standard
(ISO 25178, ISO 4287, ISO 4288, ISO 21920 and ASME B46.1)
What Roughness Tester options are available?
Basic version
Our basic roughness tester is the most budget-friendly profiler for standard components and simple roughness measurement. Its integrated manual tip/tilt stage allows to align the sample perpendicular to the optical axis.
Advanced version
In case of mid-sized samples and the need for automation, this configuration is our recommendation. It features a motorized 75 mm xy position stage with manual tip/tilt mechanism. This makes sample alignment easy and reproducible opening the door for automation and extending the measurement range by True Stitching.
