Piuma & Chiaro Probe – Stiffness 0.025 N/m – Tip Radius 10 μm

Probe used with the Piuma and/or Chiaro Nanoindenters



Piuma & Chiaro Probe – Stiffness 0.025 N/m – Tip Radius 10 μm

The Optics11 Life probes are pre-calibrated (contact based method) and reusable force sensors compatible with the Optics11 Life Nanoindenters. The probes are cantilever-based with an optical-fiber interferometric readout and are produced at our headquarters in Amsterdam.

Dependent on the application, the spring constant of the probe can be chosen between 0.025 N/m and 50 N/m which can measure elastic modulus between 10Pa and 1GPa. The unique feature of our probes is the large cantilever bending (up to 20μm) which allows to measure stiffness values spanning 3 orders of magnitude without changing the probe.

Furthermore, spherical (colloidal) glass tips mounted onto the cantilever can be chosen from 3 µm to 250 µm in radius to perform single indentations or indentation mapping at various depths/loads and resolution.


Please note that all probes are calibrated after manufacturing. Therefore, the calibrated stiffness and tip sizes may differ from the specified order values. Calibration specifications are: Stiffness = ± 5%, Tip radius = ± 1%.
