Accurate and Reproducible Measurements for Better Productivity
Tip lifetime performance data on polished silicon wafer: 15,000 scans @ 10Hz using 1 tip!
Reproduce Best AFM Measurement
True Non-Contact Mode preserves the sharp tip end even after imaging 200 images of CrN, so-called tip check sample. CrN has a very abrasive surface that may quickly wear out the sharp tip.
Accurate AFM Topography with Low Noise Z Detector
True Sample Topography™ without piezo creep error
Our AFMs are equipped with the most effective low noise Z detectors in the field, with a noise of .02 nm over large bandwidth. This produces highly accurate sample topography, no edge overshoot and no need for calibration. Just one of the many ways Park AFM saves your time and gives you better data.
- Low noise Z detector signal is used for topography
- Low Z detector noise of 0.02 nm over a large bandwidth
- No edge overshoot at the leading and trailing edges
- Calibration needs to be done only once at the factory

Automatic data collection and analysis lets you save time
The NX20 features Park's automation control software that automatically carries out AFM measurements of a sample according to your preset procedure (recipe). It can accurately collect data, perform pattern recognition, and do analysis using its onboard Cognex board and optics module, and export with almost no user in put so you have more time to do innovative research.
