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
The 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
