Recent years have seen explosive growth in the use of organic materials, composites, or organics bound to an inorganic substrate, to solve engineering problems that traditionally were approached only with inorganics. The remarkable speed with which these new technologies are appearing is contrasted by the remarkable scarcity of non-destructive, invitro, and in-vivo techniques for characterizing the biophysical, chemical, and mechanical properties of these often delicate and nano-structured materials. Near-field scanning optical microscopy (NSOM) for quantitative evaluation of surfaces is a practical solution for this type of evaluation.
Traditional spectroscopy methods utilize ‘far-field’ light easily propagated through long distances.
However, far field light is subject to diffraction effects, whether mirrors or lenses are used. Diffraction effects limit the amount of ‘focus’ that can be achieved, thus the spatial resolution for traditional microspectroscopy systems is limited to the wavelengths used; i.e. 10 microns for IR, ~1 micron for visible wavelengths.
Products & Services
Analytical laboratory services detect, classify and/or assay chemical, material, biological, geological and environmental samples.
Focal plane arrays (FPA) are detectors consisting of a linear or two-dimensional matrix of individual detector elements, typically used at the focus of an imaging system.
Infrared (IR) spectrometers measure the wavelength and intensity of the absorption of infrared light by a sample.
Fiber lasers use optical fibers doped with low levels of rare-earth halides as the lasing medium to amplify light.
Optical spectrum analyzers (OSA) can divide a lightwave signal into its constituent wavelengths. This means that it is possible to see the spectral profile of the signal over a certain wavelength range.
