WaveMode Cantilever WM0.1Au-SS
WM0.1Au probes are used for high resolution imaging in photothermal off-resonance tapping (WaveMode). The combination of high resonance frequency and low spring constant makes them suitable for a wide range of applications in air and liquids. The reflex side of the cantilever is coated with a gold layer optimized for efficient photothermal excitation. The coating is highly reflective for standard optical beam deflection AFMs. The paddle shape design helps to minimize reflective interference from sample and to maximize the sum signal.
