Dektak150 (Stylus Profiler)

Stylus profiler:Dektak150, currently located in building 451, room 913 (as of 2023).

The stylus profiler Dektak150 is intended for profile measurements on samples outside the cleanroom. The Dektak150 is especially well suited for measuring soft samples as it can be adjusted to apply lower force than the other stylus profilers at Nanolab.

The user manual, technical information and contact information can be found in LabManager.

The computer is not connected to the network but data can be saved on a dedicated USB and transfered to a computer on the network.

Info about measurement accuracy can be found here (measured with Dektak XTA).
