Near-Field Illumination


Depending on the spectral range of the Near-Field Illumination Unit, the neaSNOM microscope can be used to analyze chemical, structural and electronic properties of organic and inorganic materials with up to 1000-times better spatial resolution when compared with conventional technology such as FT-IR.
neaspec’s Near-Field Illumination Units include on-site installation, on-site verification of performance, as well as a on-site comprehensive user training and professional support.
