Cantilever & tip details

LprobeNanoFTIR_spectra+03_A2-A2-30
  • Tilted tip design
    Compensates for the AFM head’s mounting angle, ensuring accurate data on diverse sample surfaces.
  • Tip height >30 µm
    Optimal optical access for s-SNOM mode
  • Half-cone angle < 10° over the last 10 µm 
    Minimizes tip-sample convolution, ensuring more accurate morphological measurements.
  • Coating for spectroscopy
    Thick gold layer all faces of the tip, typical apex radius is 75nm. The coating is optimized for s-SNOM spectroscopy.

 

Special packaging

Spectroscopy and images with SNOM tips that have been packaged in standard AFM Gel-Pak boxes can lead to artifacts in the optical response. This is due to contamination of the tip by a few molecules of the gel. Vmicro has developed a back-end process with special decontamination and storage in a metal box. You can select this feature as an option when selecting your reference.
