    • A wafer of High quality etched silicon probes for contact mode imaging in air.

      Unmounted for use on standard AFM's.

      Bruker AFM Probes has introduced an improved version of its popular, ESP/ESPA AFM probes. Bruker’s new line of ESP high quality premium etched silicon probes set the industry standard for contact mode 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 ESPW-V2.

      The current model ESPW is available for ordering through early 2015 at which point, it will become obsolete.


    • Tip Geometry: Standard (Steep)

    • Aluminum reflective coating on the backside of the cantilever. The Al Reflective coating 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, highly reflective samples, and machine vision applications.
