Measurement of submicron particle by NFIR

Research and development of microstructure which is called nanotechnology have been expanding in the field of several devices such as semiconductors and liquid crystals. Moreover in the field of life science, nanoscale studies such as structure and function of biological tissue are now expanding rapidly. Vibrational spectroscopy is an extremely efficient method for analyzing molecular structure and chemical binding easily for those purposes without destruction, however, since the spatial resolution depends on the wavelength of the light applied, the size of the measurement area has been limited to 1 mm by Raman spectroscopy and 10 mm by conventional transmittance infrared spectroscopy. However, measurement in the area of submicrons is now getting capable by near field infrared spectroscopy system using a light scattering probe.

Spectrum measurement of a submicron particle will be explained in this application data.
