A profilometer is used to measure surface profiles to determine the roughness of surfaces. The Dektak 150 is a contact stylus profilometer. The diamond tip stylus is run over a sample surface and records height differences which is sent to a computer.

Materials allowed: everything which is not considered as contaminating within NanoLab rules, sample size can’t exceed 150 mm in diameter and 90 mm in height.

• Scan length range: 55 mm
• Vertical range: 524 µm
• Vertical resolution: 1 Å maximum (at 6.55 µm range)
• 12.5 µm diamond tip stylus
