The Bruker PI 85 Picoindenter is an in situ mechanical testing device that operates within a SEM. Video capture of the SEM signal allows correlation of the images with mechanical testing results. The SEM picoindenter is equipped with a standard transducer with a max force of 10 mN and a high load transducer with a max force if 100 mN. A 5 µm flat punch probe and a cube corner probe are available for both transducers.

This is an accordion element with a series of buttons that open and close related content panels.
