Apreo 2 SEM

Field Emission Scanning Electron Microscope (FESEM) for versatile, high-performance materials imaging and analysis.

Thermo Scientific Apreo 2 is a Schottky Field Emission SEM (FESEM) that delivers ultra-high resolution across both high- and low-voltage applications. Its electrostatic lens design and low vacuum mode enable superior charge compensation for non-conductive materials. Equipped with beam deceleration and unique in-lens detection, the system provides unmatched contrast and versatility for researchers analyzing diverse materials and devices.

The Apreo 2 SEM makes high-performance imaging and analysis accessible to all users, regardless of expertise. Its groundbreaking ChemiSEM Technology offers live elemental imaging through an intuitive interface, streamlining compositional analysis and eliminating traditional EDS complexities. SmartAlign Technology automates optics alignment, while FLASH Technology ensures effortless image optimization empowering even beginners to achieve professional-grade results.

Setting a new standard, the Apreo 2 achieves 1 nm resolution at a 10 mm analytical working distance, maintaining exceptional imaging clarity even at extended distances. With its user-centric design and advanced automation, the Apreo 2 enables anyone to obtain precise, publication-ready results with confidence.

Features

High performance, resolution, and contrast

The combination of advanced optics, detection and automation in Apreo 2 makes obtaining high resolution imaging possible even for users new to SEM.

Wide range of sample types

Apreo 2 was designed for maximum flexibility. High quality, high resolution imaging is possible regardless of target samples properties. Insulators, beam sensitive or magnetic materials can all be imaged with ease thanks to Apreo 2's unique optics, detection and beam control options.

Live quantitative EDS with ChemiSEM

Elemental information at your fingertips with ChemiSEM, which provides live quantitative elemental mapping for unprecedented time to result and ease of use.

Quick and easy sample loading

Easy access to the stage, a convenient multi-sample holder, and a fast pump down ensures no time is wasted loading samples. An automated routine to insert and remove a pressure limiting aperture (PLA) allows for a seamless switch between high and low vacuum without opening the chamber.

Advanced automation

From optics, to image acquisition, Apreo 2 provides a range of automated features to make imaging time as effective and efficient as possible. Flash Technology automates image fine tuning The unique Undo function permits efficient exploration of imaging conditions Thermo Scientific Maps software automates large area acquisition with up to 4 different simultaneous signals.

Performance at long working distance

Apreo 2 is the only SEM that offers high-resolution performance (1nm) and excellent image quality at analytical working distance (10mm). Sample morphology, topography and surface information can all be simultaneously explored while being at a safe distance from the pole piece. Thanks to its high-speed and high-sensitivity in-lens backscattered detector, BSE are still detected even at extremely low beam currents (as low as few pA).
