The interaction of liquids with a solid surface exhibits various interesting effects, e.g. the lotus effect. The characterization of surface wetting is usually performed by measuring the contact angle. Our self-constructed measurement setup contains different 3D-printed parts and is based on National Instruments LabView offering many useful features:

• Various fitting algorithms (circle, ellipse, spline, polynomial)

• Measurement in live videos or static images

• Semi-automated measurements

• Sample tilting with precision <0.1°
