Model 1040 – NanoMill UHR TEM Sample Preparation System
The NanoMill is a unique system that uses an ultra-low energy, concentrated ion beam enabling removal of amorphisation, implantation, or redeposition from targeted areas to produce the highest quality specimens for transmission electron microscopy.
