InForce 50 Nanomechanical Actuator

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.

InView Control Software & CPU

The Inview Software provides for all aspects of instrument control, test design, reporting and data manipulation/analysis of nanoindentation testing. A high performance CPU is included, which interfaces with the controller via USB. Integrated video-synchronization is included on InSEM and NanoFlip Instruments, which maps acquired data to video images from the SEM.


Dynamics superimposes an oscillatory force on the Actuator load signal and measures the resultant displacement oscillation to provide a continuous measurement of the measured stiffness of the system. This data can be used to determine a continuous modulus or hardness or a continuous contact stiffness during a nanoindentation test. The ability to operate at different frequencies, load amplitudes or displacement amplitudes allows the use in a dynamic- mechanical analysis mode to provide storage and loss modulus and tan- delta.
