Surface profiling - Import export

RAMOS CARS is the multifunctional multi-channel 3D scanning laser microscope-spectrometer. RAMOS CARS is intended for simultaneous and multifunctional analysis: high-speed imaging by CARS signal; confocal Raman imaging; confocal fluorescence imaging; confocal imaging in the reflected laser radiation; high-contrast imaging in the transmitted laser radiation; as well as visualization of a surface profile by means of the second harmonics generation signal. Microscope RAMOS CARS combines in one system: - CARS scanning microscope - Raman/luminescent scanning confocal microscope - Conventional scanning confocal laser microscope Applications: - Nanobiotechnology: real-time noninvasive analysis of biological samples (cells and components of living cells) with high spatial resolution. - Micro- and nanotechnology investigations of properties of non-biological microstructures: semiconductors, liquid crystals, polymers, pharmaceutical components, micro- and nanoparticles.

Operating a scanning probe microscope, where the tipsample force interactions are measured with high precision and at small scales, requires an environment that is free of the external perturbations caused by vibrational and acoustic noise. Just as important is the temperature stability of the microscope in order to ensure a low thermal drift of a sample during experiments. A unique feature of Atomic Force Microscopy (AFM) and Scanning Tunneling Microscopy (STM) is a relatively slow feedback mechanism in most of their modes. Therefore, a large number of experiments such as imaging at the atomicscale, profiling of corrugated surfaces, collecting of local force curves in the force volume operation, among others will benefit from lowthermal drift conditions. A stable position of the sample will also help to examine the same surface region with different AFM modes, making the surface analysis more comprehensive.
