Our Dektak ST3 and 3030 scanning stylus profilometers are capable of scanning over 50 mm distances with height sensitivity of about 1 nanometer. The instruments use a 12.5um diamond stylus that can be set to as light a load as 10mg.

Traceable measurements can be made using our MRS-3 or MRS-4 calibration standards.

We can measure flat or curved surfaces to determine Ra, Rq, Skew, etc.

We can scan over very soft materials without leaving tracks.

Data from the ST3 can be transferred to a computer for specialized analysis in your Matlab application.
