Overview
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 & aesthetics  

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

Tip Specification
FESPA-V2 Tip Image
Tip Height (h): 10 - 15 µm
Front Angle (FA): 25 ± 2.5º
Back Angle (BA): 15 ± 2.5º
Side Angle (SA): 22.5 ± 2.5º
Cantilever Specification
FESPA-V2 Cantilever Image
The Aluminum reflective coating on the backside of the cantilever increases the laser signal (A+B) by up to 2.5 times. Although not necessary for general imaging, reflective coating is recommended for thin cantilevers (< 2.5 µm), highly reflective samples, and machine vision applications.
Material: 0.01 - 0.025 Ωcm Antimony (n) doped Si
Geometry: Rectangular
Cantilevers Number: 1
Cantilever Thickness (Nom): 2.75µm
Cantilever Thickness (RNG): 2.0 - 3.5µm
Back Side Coating: Reflective Aluminum
