TGZ2

Calibration grating TGZ2 is intended for Z-axis calibration (step height 110 ± 2 nm) and nonlinearity measurements.



* Step height is the average meaning based on the measurements of 5 gratings with the same height (from the batch of 300 gratings) by AFM calibrated wih help of PTB certified grating TGZ1. Basic step height can vary from the specified one within ±20 % depending on the batch (for example TGZ2 grating can have step height 95±2 nm).
