Near Field Illumination Units

Ready-to-use VIS, NIR, MIR and even THz Near-Field Illumination Units with Guaranteed Performance

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.
