AFM Options

Customize your AFM to handle any project

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.

Sample Tilting Stage for Sidewall Imaging lets you see more


The NX20’s innovative architecture lets you detect the sidewall and surface of the sample, and measure their angle. This gives the unit the versatility you need to do more innovative research and gain deeper insights.


Active Temperature Controlled Acoustic Enclosure

Innovative control design allows Park NX20 to quickly reach temperature equilibrium
Park NX20 also features active vibration isolation.

Encoders for Motorized Stage

• The encoded XY stage travels in 1 µm resolution with 2 µm repeatability
• The encoded Z stage travels in 0.1 µm resolution with 1 µm repeatability

Sample Plates

• Dedicated small sample holder for electrical measurements
• Vacuum grooves to hold wafers

Temperature Control

· Temperature Controlled Stage 1:  -25 °C to +170 °C
· Temperature Controlled Stage 2:  Ambient to +250 °C
· Temperature Controlled Stage 3:  Ambient to +600 °C
