Product Description:

***Note: The final day for ordering the TESPAW probe will be January 31, 2015, after which point, it will become obsolete and replaced by the new model TESPAW-V2. Read the TESPAW obsolescence notification letter here and contact your local Bruker representative if you have any questions or concerns.

Bruker's premier line of etched silicon probes are the industry standardfor imaging in TappingMode and non-contact mode in air.  Tightspecification control, unrivaled sensitivity, and dependably sharp tipsall contribute to producing consistently accurate, high-resolutionimages. 

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

For a probe with similar specifications at a lower cost try the NCHV-AW probe, part of Bruker's VALUE line!

Tip Specification

*Due to the inherent danger of mishandling or contamination during extraction of probes by non-Bruker personnel, we do not guarantee performance of wafers once opened at the consumers site. Instead, we highly recommend buying in larger quantities of 10-packs to guarantee performance, taking advantage of quantity discount pricing.
Geometry: Standard (Steep)
Tip Height (h): 10 - 15µm
Front Angle (FA): 25 ± 2.5º
Back Angle (BA): 15 ± 2.5 º

Cantilever Specification

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.
