Simpler, More Stable, More Quantitative AFM Imaging with Asylums blueDrive
New blueDrive Photothermal Excitation for Asylum Research Cypher AFMs uses a modulated blue laser to directly drive the cantilever during AC mode imaging, producing an ideal frequency and phase response.
AC modes typically rely on piezoacoustic drive, which in liquid produces an obviously distorted and time-varying response. In air, the high Q of the lever can mask the problem, but it still interferes with quantitative analysis.
blueDrive enables simpler, more stable, and more quantitative results whether using tapping mode for high resolution topographical imaging or techniques like AM-FM or Contact Resonance Viscoelastic Mapping Modes to measure nanomechanical properties.
