ZTS-9020 / ZTS-9050 / ZTS-9090

A high-speed, precision surface profiling inspection sensor for shop-floor installation.

Non-contact 3D Surface Profiling Sensor

Optimized for very high resolution surface profiling of cylindrical structures, the ZeroTouch® ZTS-9000 Series system can scan cylinders up to 200mm in depth.

Fast, Precise 3D Surface Measurements

The ZeroTouch® 9000 Series sensor evaluates several thousand surface profiles using advanced white-light interferometry technology to capture high-speed, precision data acquisition and real-time 3D surface roughness measurements. Using high-resolution cameras, the sensor provides highly significant results without the limits of tactile measuring systems.

Determination of honing angle and volume parameters.

Surface Measurements

High-resolution cameras measure both smooth and rough specimen surfaces without contact, characterizing mechanically processed surfaces such as mirrors, semiconductor wafers, micro-lenses, glass, metal, plastic, composite, or other surfaces.


Precision Height Mapping

The sensor works with interference objectives from 5x to 100x, yielding fast, precise representation of the height information and the relevant surface parameters using a piezo objective adjuster and broadband wavelength spectrum lighting.


ISO Conform Roughness Measurements

Objectives starting from 10x and higher can be used for ISO confirm roughness measurements in accordance with ISO 25178 and ISO 4287.

Benefits of Consolidating Metrology Operations

Automated metrology platforms not only ensure high quality finished goods, these high speed solutions also lower total cost per part by consolidating multiple metrology operations into one system.

Improving Long-Term Performance of Metrology Systems

In challenging manufacturing environments, adjustability, calibration, and monitoring are key influences on the long-term performance of automated metrology systems installed in uncontrolled environments.

Speed Wins in Contact vs. Non-Contact Surface Profiling

In surface morphology inspection, non-contact optical methodologies provide the same measurement results as a conventional contact profiler—but in a fraction of time.
