Product Description:

A pack of 10 High quality long-lever etched silicon probes for TappingMode™ and other non-contact modes.  Unmounted for use on standard AFM's.

Bruker AFM Probes has introduced an improved version of its popular, LTESP/LTESPA AFM probes. Bruker’s new line of LTESP high quality premium etched silicon probes set the industry standard for long-lever TappingMode™ and non-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 & aesthetics  

This AFM probe is unmounted for use on any AFM and is also available with Aluminum reflex coating as model LTESP-V2.  

The current model LTESP is available for ordering through early 2014 at which point, it will become obsolete.
