neaSNOM Microscope - Where Optical Imaging & Spectroscopy meets AFM

Based on neaspec¡¯s revolutionary technology, neaSNOM is the only microscope on the market capable of imaging & spectroscopy in the visible, infrared and even terahertz spectral region at only 10 nm spatial resolution.

This makes neaSNOM the ideal tool for cutting-edge nanoanalytic applications such as chemical nano-composition (nano-FTIR-mode), nano-plasmonic fields, nanoscale stress/strain fields and free charge carrier distributions. Many scientists around the world trust in technology from neaspec for their publications in Nature, Science and other high impact journals.
