Improving Micro-Raman/AFM Imaging Using Negative-Stiffness Vibration Isolation

Facebook X LinkedIn Email
By Jim McMahon

Negative-stiffness vibration isolators can easily support the heavy weight of a combined AFM/micro-Raman system, and isolate it from low frequency vibrations more effectively than high-performance air tables or active isolation systems. The need for precise vibration isolation with scanning probe microscopy (SPM) and near-field scanning optical microscopy (NSOM) systems is becoming more critical as resolutions continue to bridge from micro to nano. Whether used in academic labs or commercial facilities, SPM and NSOM systems are extremely susceptible to vibrations from the environment....Read full article

    atomic force microscope
    An atomic force microscope (AFM) is a high-resolution imaging and measurement instrument used in nanotechnology, materials science, and biology. It is a type of scanning probe microscope that operates by scanning a sharp tip (usually a few nanometers in diameter) over the surface of a sample at a very close distance. The tip interacts with the sample's surface forces, providing detailed information about the sample's topography and properties at the nanoscale. Key features and principles of...
    nano
    An SI prefix meaning one billionth (10-9). Nano can also be used to indicate the study of atoms, molecules and other structures and particles on the nanometer scale. Nano-optics (also referred to as nanophotonics), for example, is the study of how light and light-matter interactions behave on the nanometer scale. See nanophotonics.
    nanotechnology
    The use of atoms, molecules and molecular-scale structures to enhance existing technology and develop new materials and devices. The goal of this technology is to manipulate atomic and molecular particles to create devices that are thousands of times smaller and faster than those of the current microtechnologies.
