Meet the Chiaro


Optimized for microscopes

The Chiaro Nanoindenter is compatible with almost any inverted microscope to enable microscopy to be combined with force sensing simultaneously.

Independent mounting

Due to the almost limitless mounting options and low footprint of our nanoindentation probes, the Chiaro can be combined with many microscopes or other optical set-ups, even simultaneous with other instruments such as electrophysiology equipment, patch clamping instruments, perfusion or heating stage chambers, and many more!

Complete package

Even the standard version of the Chiaro Nanoindenter includes all the tools required to perform advances force sensing experiments, such as obtaining the Young’s Modulus of living cells.

Chiaro technology

Our nanoindenter instruments provide highly accurate and precise measurements of any sample in any environment with high speed and ease of use. These unique capabilities are enabled by making use of the Optics11 patented micro-machined fiber-optical sensors. The Piuma and Chiaro nanoindenters use this sensor to gently push a spherical glass tip on the surface of the sample. By closely monitoring the resulting sample deformation, the nanoindenter can rapidly provide all mechanical details of the indented spot, both under static and dynamic operation.
