Atomic Force Microscopes NP-AFM AFM workshop

The NP-AFM is a nanoprofiler for analysis of features such as surface roughness and metrology of technical samples. Primary applications for the NP-AFM include process development and process control of technical samples.

High Resolution Video Microscope	Readily locate Features for Scanning
Multiple Sample Stage or Vacuum Chuck	Optimized for specific technical samples
Closed Loop XY scanner	Great accuracy with rapid zoom to feature
Probe Exchange Tool	Reduce time for probe exchange
In plane flexure XY scanner	Minimal out of plane motion in images
Labview software with USB communication	Readily adaptable to new operating systems
Uses Industry standard probes	Probes for specific measurements are readily available.
Includes Vibrating, Non-Vibrating modes	Turnkey system
