TNTG Series Single Calibration Gratings

A range of single gratings for calibrating different AFM axes on different length scales. Most of the gratings can also be purchased as part of a set which is often cheaper depending on user requirements. Please see product variation table for the different available options.

Key Features


  • Gratings are etched into a piece of Silicon 5x5mm with a thickness of 0.5mm and are glued onto a metal sample carrier suitable for AFM
  • The etched area for calibration is typically the central 3x3mm of the 5x5mm piece
  • They are supplied in a plastic case complete with GelPak® for storage when not in use.

Please check all the images in the image gallery or our data sheet for more detail on the structure of each grating type.
