Nanomechanical Actuator for Nanoindenter

The Nanomechanics InForce actuators utilize patent-pending voice-coil force generation and capacitive displacement measurement to achieve the best dynamic range in the industry.
With 50mN of force, the InForce 50 enables a wide range of compressive, tensile and nanoindentation testing. The dynamic characteristics of the head mean that low-noise, stability and closed-loop control are inherent to the design, whether operating in quasi-static or dynamic modes.
