Contact Resonance Viscoelastic Mapping Mode

Contact Resonance Viscoelastic Mapping Mode for Cypher AFMs excels at quantitative mapping of both elasticity and viscoelastic damping for materials in the ~1 GPa to 100’s GPa modulus range. Asylum’s exclusive Dual AC™ Resonance Tracking (DART) technology improves the sensitivity and accuracy of the technique. Precise wide-band, frequency-independent actuation is available by either piezo drive (sample or cantilever) or blueDrive photothermal excitation. 

• Contact mode technique that measures both storage modulus, E’, and loss modulus, E’’
• Good for samples from 1 GPa to 300 GPa
