Near-field scanning optical microscopy (NSOM/SNOM) is a microscopy technique for nanostructure investigation that breaks the far field resolution limit by exploiting the properties of evanescent waves. In SNOM, the excitation laser light is focused through an aperture with a diameter smaller than the excitation wavelength, resulting in an evanescent field (or near-field) on the far side of the aperture. When the sample is scanned at a small distance below the aperture, the optical resolution of transmitted or reflected light is limited only by the diameter of the aperture. In particular, lateral resolution of 20 nm and vertical resolution of 2–5 nm have been demonstrated.
The global market for Near-Field Scanning Optical Microscopy (NSOM) is expected to reach about 64.3 Million USD by 2025 from 48.5 Million USD in 2018, registering a Compounded Annual Growth Rate (CAGR) of 4.1% during the analysis period, 2019-2025.
The key players are NT-MDT, Witec, Neaspec, Nanonics imaging, Anasys Instruments (Bruker), A.P.E. Research, Mad City Labs Inc and so on.
