Substage with 20 mm travel

Our range of stages are suited for orthogonal positioning solutions in atmosphere, SEM/FIB, UHV and at low temperatures.

The LT6620 is primarily used in SEM/FIB to enhance the accuracy and functionality of the standard microscope stage. It is designed for large-range high-precision applications in extreme environments.

It is not fitted with positional encoders and is thus the economical alternative to the LT6820 substage for applications where repeatability or automization is not required.
