Product Description

Calibrated Unique probes with Single Crystal Diamond tip specially designed for Nanoindentation, Nanoscratching, Lithography etc. Resonant frequency 500-1000kHz, force constant 100-600 N/m, curvature radius <15nm.

These tips are specifically designed for high mechanical loads and scratch testing applications. By using wear-resistant diamond and a board cone angle the contact size is well characterized and stays constant during repeated mechanical measurements. These probes have demonstrated highly repeatable deep (~100nm) indentations into materials such as fused silica and are able to image the indents at high resolution in-situ using the same probe. A gold reflex coating deposited on the detector side of the cantilever to enhance the reflectance of the laser beam.

The probes are shipped with individually measured spring constant and a high resolution SEM image showing tip radius and cone angle.  These probes are essentional for highly accurate nanoindentation and quantitative nanomechanics for materials in the 10-100 GPa range. 

Nominal values: force constant - 350 N/m, resonance frequency – 750 kHz.
