Atomic Force Microscope designed for easy integration into the Scanning Electron Microscopes. The combination of complementary AFM and SEM techniques enables you to use the advantages of both commonly used microscopy techniques.
LiteScope supports a variety of self-sensing probes through proprietary probe holders.
LiteScope is not limited by the use of proprietary AFM probes but supports a broad variety of self-sensing probes from other manufacturers through appropriate probe holders. AFM probe can be easily inserted into the appropriate probe holder and then attached to the LiteScope’s universal holder acceptor – no screws or tools required.
The use of quartz crystal tuning fork for AFM application is based on the effect of high-Q resonance detuning when the tip mounted on the oscillating quartz approaches the surface. Tuning fork-based probes possess many advantageous properties such as high stiffness, stable oscillation, direct electrical actuation, and low-cost.
Silicon cantilevers with an integrated piezo‐resistor are available in many different specifications suitable for various applications.
PRSA - with an integrated piezo-resistor bridge and a thermal heater for self-sensing and self-actuating.
PRS - with an integrated piezo-resistor bridge, without a thermal heater

The nanoindentation module is a new module for the Atomic Force Microscope LiteScope. It allows to do quantitative measurements of mechanical porperties of samples, combined with AFM analysis during real time observation in SEM. Whole device can by attached and detached at any time, offering the choice between regular corelated AFM + SEM measurements or a unique combination of nanoindenter and AFM both in SEM.
The sample rotation module for AFM-in-SEM LiteScope enables mounting several samples into the SEM chamber simultaneously and performing their AFM and SEM correlative measurements without opening the chamber. The rotation module is also extremely useful for FIB milling procedures followed by an AFM analysis.
NenoCase is a new accessory for an Atomic Force Microscope LiteScope.
NenoCase is not only a user-friendly storage case but it also brings new possibilities that allow LiteScope to perform as a stand-alone device. It incorporates a passive anti-vibration system to ensure high-quality imaging outside the SEM chamber.
NenoCase can be purged with different gases used for measurements under different atmospheres.
A digital camera with a custom-made stand is an optional NenoCase accessory that allows precise optical AFM tip navigation on the sample surface. The camera control is integrated directly into the NenoView software which enables long working distance.
LiteScope load-lock mechanism provides the possibility of loading samples and probes into LiteScope using a standard SEM air-lock / load-lock sample transfer system.
Load lock is an optional accessory for LiteScope, which enables quick and easy sample and/or AFM probe exchange without the need for disrupting the high vacuum in the SEM chamber.
The semi-automatic loading system consists of two adaptation arms:
Key Features/ Advantages
LiteScope is compatible with many standard SEM stubs; nevertheless, custom stubs, sample holders, or a variety of specialized tools can be tailored for specific AFM-in-SEM applications.
AFM-in-SEM approach gives access to measurements and applications that were not possible with separate AFM and SEM systems. All the way from heated/cooled stage for e.g. life-science applications to a micro tensile tester for e.g. characterization of metals – let us know about your requirements to be able to take full advantage of the AFM-in-SEM concept.
