The Attension Theta Optical Tensiometer with 3D Topography Module

This white paper introduces the Attension Theta Flex Optical Tensiometer with 3D Topography Module, which enables automated, simultaneous measurement of surface roughness and contact angle on the same sample. It explains the underlying measurement principles, the calculation of roughness-corrected contact angles using the Wenzel equation, and highlights key application areas such as material adhesion, biocompatibility, and surface coatings.
