Optical Micro Tips

Optical Micro Tips for Near Field Microscopy (SNOM) applications

K-Tek provides three standard fiber optic options that are designed for Near-Field Scanning Optical Microscopy (NSOM/SNOM) and will cover most applications.

Optical Micro Tips for Near Field Microscopy (SNOM) applications:

  • Light proof aluminium coating on titanium layer
  • All our tips are individually light leakage proved at 400μW, 532nm
  • Ready for tuning forks (10mm jacket stripping) and shear force
