Thermo Scientific, Hillsboro, Oregon, has developed the Apreo scanning electron microscope, which features a revolutionary compound lens design that combines electrostatic and magnetic immersion technology to yield unprecedented resolution and signal selection. This makes the Apreo SEM the platform of choice for research on nanoparticles, catalysts, powders and nanodevices, without compromising on magnetic sample performance.
The unique compound final lens delivers an exceptional resolution of 1.0 nm at 1 kV, without the need for beam deceleration – on any sample, even if it is tilted or topographic. The most useful backscatter detection: materials contrast is always available, even at low voltage and beam currents, at any tilt angle, on beam sensitive samples and at TV-rate imaging.
The Apreo SEM benefits from the unique in-lens backscatter detection, which provides excellent materials contrast, even at tilt, short working distance, or on sensitive samples. The novel compound lens further improves contrast with energy filtering, and adds charge filtering for imaging of insulating samples.
The optional low vacuum mode now has a 500 Pa maximum chamber pressure for imaging even the most demanding insulators.It features unparalleled detector flexibility,making it possible to obtain the contrast or signal intensity that matters most by combining information from individual detector segments.
