RTESPA-150-30

Product Description:

Building on Bruker’s flagship series of Tapping probes with rotated tip, the RTESPA-150-30 provides accurate nanomechanical mapping on soft samples in air with controlled end radius and laser Doppler vibrometer calibrated spring constants.

End radii are controlled to 30nm +/- 15%. Spring constants are individually calibrated and guaranteed within 10% . Parameters are contained in the QR code on the box for fast and error free reading with the QR reader included with Bruker’s new PeakForce QNM high accuracy kit available for Dimension Icon. The moderately low nominal 5N/m spring constant is most suitable for soft polymer samples (typically in MPa range). For other samples, see the whole series of calibrated probes.

- Nanomechanical mapping with FFV or PFQNM on Dimension Icon
- Controlled 30nm end radius
- Individually calibrated spring constant, 5N/m nominal
- Parameters contained in QR code
- One pack of 5 probes

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.
