Lateral-(XY)-Calibration Standard

The standard (2D200) is used for a very precise x-y-calibration of the scanning mechanism. The standard consists of a 2-dimensional lattice of inverted square pyramids with 300nm pitch etched into a silicon chip.


  • 200 nm pitch
  • high accuracy

The silicon chip is glued onto a stainless steel sample holder with 12 mm diameter. This holder can be magnetically or mechanically fixed. The product will be shipped in a Gel-Pak® carrier.

This standard has been developed in close cooperation with the German national authority of standards: PTB (Physikalisch Technische Bundesanstalt). Due to this PTB is able to certify this standard in accordance with international guidelines. Please contact Working Group 5.25 Scanning Probe Metrology at www.ptb.de directly.
