Imaging & Spectroscopy Modules

Neaspec

For optical imaging & spectroscopy with nanoscale spatial resolution, the neaSNOM microscope can be equipped with different Near-Field Detection Modules. For operation also a Near-Field Illumination Unit is required. Illumination units are available in the visible, NIR and MIR spectral range.
