Natural Test Materials and Calibration Gratings for Scanning Probe Microscope (SPM) from NT-MDT

Scanning probe microscopy has something in common with the sphere of music. No musical instruments can be played without preliminary adjustment through tuning fork that is the "all-known" gold standard of a sound in the field of music.

Scanning probe microscopy doesn't yield to any musical instruments in respect to complicity, and for accurate and correct operations, scanning probe microscopy should be adjusted at least once every six months. In the world of scanning probe microscopy, the gold standard of adjustment is the calibration grating.

Everyone who is involved with nanotechnology knows the price of mistake when their SPM is uncalibrated or improperly calibrated. With the help of NT-MDT test samples and calibration gratings, it's possible to verify accuracy and to find errors in SPM calculations. The calibration gratings are made of silicon, thus it is possible to achieve accuracy in instrument readings due to absolute predictability of silicon natural structure.

NT-MDT and its' products including accessories are certified by ISO 9001:2008. Moreover all NT-MDT calibration gratings are included in Russian public register as measurement instrumentations. NT-MDT calibration gratings also has Europe (PTB) certifications and can be supplied with calibration certificate of international standard as well.

Enjoy correct measurements with NT-MDT calibration gratings.
