FESPA-V2

FESPA-V2

2.8N/m, 75kHz, 4 Sided Tip, Al Reflex Coating, 10-Pack

  • A pack of 10 High quality etched silicon probes for soft TappingMode™ imaging and force modulation in air. 

    Unmounted for use on standard AFM's.

    Bruker AFM Probes has introduced an improved version of its popular,FESP/FESPA AFM probes. Bruker’s new line of FESP high quality premiumetched silicon probes set the industry standard for soft TappingMode imaging and force modulation in air.

    The new design provides:

    •   Tighter dimensional specifications for improved probe to probe consistency
    •   Tighter alignment of the tip apex to the cantilever resulting in easier laser positioning over the tip
    • Improved probe quality and aesthetics

    This AFM probe is unmounted for use on any AFM and is also available without Aluminum reflex coating as model FESP-V2.
