Quick Overview

Specially designed probes for high mechanical loads and scratch testing applications. Each probe includes a high resolution SEM showing the tip radius and cone angle, see QR code.

f = 750 kHz   |   k = 350 N/m   |   tip coating: diamond tip

Product Name Price Qty
NM-TC (5 Pack)
(Ships in 1-2 Weeks)


The probes feature wear-resistant diamond tips and a broad cone angle, such that the contact size is well characterized and stays constant during repeated mechanical measurements. Each probe comes individually characterized by SEM to accurately measure the tip shape. A gold reflex coating deposited on the detector side of the cantilever to enhance the reflectance of the laser beam. A premium version of this probes is available as model NM-RC-C, which has a tighter cone angle specification and includes spring constant calibration.
