The neaSNOM microscope can be equipped with different Near-Field Detection Modules
The award winning microscope design allows 180° optical access to AFM-tip and dual beam access with up to two near-field detection modules for e.g. imaging (left side) & for spectroscopy (right side).
Note: For operation also a Near-Field Illumination Unit is required (available in the visible, NIR, MIR and THz spectral range).
