Photothermal Excitation For Atomic Force Microscopy
- Created: Wednesday, 01 January 2014
Asylum Research (Santa Barbara, CA), an Oxford Instruments company, has announced blueDrive photothermal excitation, an option available exclusively for Asylum’s Cypher™ Atomic Force Microscopes (AFMs). blueDrive makes tapping mode imaging simple, stable, and accurate. blueDrive replaces the conventional piezoacoustic excitation mechanism, instead using a blue laser to directly excite the AFM cantilever photothermally. This results in an ideal cantilever drive response in both air and liquids, which provides significant performance and ease of use benefits for tapping mode imaging.
blueDrive is available exclusively on the Asylum Research Cypher S and Cypher ES AFMs and is compatible with the full range of tapping mode techniques in air and liquid including topographic imaging, phase imaging, electric force microscopy (EFM), Kelvin probe force microscopy (KPFM, or surface potential imaging), magnetic force microscopy (MFM), and AM-FM and Contact Resonance Viscoelastic Mapping Modes.
