Request InfoOxford Instruments Asylum ResearchAsylum Research has announced blueDrive photothermal excitation, an option available for its Cypher atomic force microscopes (AFMs). The process uses a blue laser to photothermally excite the AFM cantilever, resulting in improved cantilever drive response in both air and liquids. The option is available on the company’s Cypher S and Cypher ES AFMs and is compatible with a variety of tapping mode techniques, including topographic and phase imaging; electric force, Kelvin probe force and magnetic force microscopy; and AM-FM and Contact Resonance Viscoelastic Mapping.
