K-TEK Nano Grating set TGS1 consists of 3 calibration gratings: TGZ1, TGZ2, TGZ3
TGZ series is intended for Z-axis calibration of scanning probe microscopes (SPM) and non-linearity measurements. Each grating offers a different step height.
Now the calibration grating set TGS1 which consists of three gratings TGZ1, TGZ2, TGZ3 is available with PTB tracable certificate. Ordering grating set TGS1 with code TGS1_PTB you will get the gratings with PTB traceable certificate. The gratings TGS1_PTB are measured on the SPM which has been preliminary calibrated using the PTB certified grating set TGS1.
K-TEK Nano Calibration Grating Set TGS1 description:
Structure: • Si wafer • the grating is formed on the layer of SiO2 Pattern types: 1- Dimensional (in Z-axis direction) Step height: • TGZ1 - 18.5±1 nm* • TGZ2 - 108.5±2 nm* • TGZ3 - 535±2.5 nm * Period: 3±0,01µm Chip size: 5x5x0,5mm Effective area: central diameter 3x3mm
* the average meaning based on the measurements in 5 points of each grating on the SPM calibrated by PTB certified grating set TGS1.
