Background

NT-MDT Co. was established in 1991 with the purpose to apply all accumulated experience and knowledge in the field of nanotechnology to supply researchers with the instruments suitable to solve any possible task laying in nanometer scale dimensions. The company NT-MDT was founded in Zelenograd - the center of Russian Microelectronics. The products development are based on the combination of the MEMS technology, power of modern software, use of high-end microelectronic components and precision mechanical parts. As a commercial enterprise NT-MDT Co. exists from 1993.

Natural Test Samples and Calibration Gratings 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.
