ASNOM (homemade)

Apertureless Scanning Near-Field Optical Microscope (homemade)

asnom

The ASNOM system was developed in-house based on the existing  Q-Scope 350 SPM
Imaging modes: scattering-Scanning Near-Field Optical Microscopy (s-SNOM), Second Harmonic Generation Scanning Near-Field Optical Microscopy (SHG-SNOM), Fluorescence Apertureless Scanning Near-Field Optical Microscopy (FASNOM)

Key features:
  • Optical resolutions of  less than 30 nm
  • Background free pseudo-heterodyne detection
