Park NX-PTR features

Low Noise XYZ Position Sensors for more accurate scans

The NX-PTR provides you with unprecedented accuracy in topography height measurement by utilizing its ultra-low noise Z detector instead of the commonly used Z voltage signal that is non-linear in nature. Industry leading low noise Z detector replace the applied Z voltage as the topography signal and make the forward and backward scan gap a negligible 0.15% of the scan range.

Minimal Thermal Drift and Hysteresis reduces tip drift

The body of the NX-PTR is designed to be extremely mechanically and thermally stable, minimizing thermal drift and giving you more precise measurements. A typical thermal drift rate is less than 100 nm/°C for the lateral direction and 200 nm/°C for the vertical direction.

Automatic Measurement Control so you can get accurate scans with less work

aotomatic-softwareThe NX-PTR is equipped with automated software that makes operation nearly effortless. Just select the desired measurement program to get precise multi-site analysis with optimized setting for cantilever tuning, scan rate, gain, and set point parameters. Park's user-friendly software interface gives you the flexibility to create customized operation routines so you can access the full power of the NX-PTR and get the measurements you need. Creating new routines is easy. It takes about 10 minutes to create a new routine from scratch, or less than 5 minutes to modify an existing one.

Park NX-PTR’s automated system features

• Auto, semi-auto, and manual mode so you have complete control
• Editable measurement method for each automated routine
• Live monitoring of the measurement process
• Automatic analysis of acquired measurement data
