Users report faster results, with high-resolution imaging possible regardless of prior SEM expertise.

Resolution and Performance at Long Distances

Unlike competitors, the Apreo 2 maintains 1 nm resolution at 10 mm working distance, crucial for analyzing sensitive or large samples safely.

Its high-sensitivity in-lens backscattered electron detector captures clear images even at low beam currents as few as pA.

This enables detailed surface topography and material contrast on insulators, beam-sensitive, or magnetic specimens without artifacts.

Labs handling nanoparticles, like palladium on cerium oxide or platinum particles, benefit from highlighted contrasts previously hard to detect.

The Trinity detection system swiftly provides comprehensive sample insights, accelerating research workflows.

Versatility Across Sample Types

Apreo 2 handles a broad spectrum of materials, from conductive metals to challenging non-conductive or dynamic samples.

Advanced beam control and detection options ensure high-quality imaging without sample preparation modifications.

Researchers characterize samples in their natural state, preserving integrity for accurate analysis.

This versatility supports applications in semiconductors, battery materials, pharmaceuticals, and advanced composites.

Multi-modal microanalysis including EDX, EBSD, WDS, and CL meets diverse lab needs seamlessly.

Automation Driving Lab Efficiency

Automation permeates the Apreo 2 design, from optics alignment to large-area imaging.

Maps software enables automated acquisition with up to four simultaneous signals, ideal for montaging complex structures.

An innovative Undo function allows rapid exploration of imaging parameters without data loss.

These tools cut imaging time, boosting productivity in high-throughput environments.

Lab managers value the reduced training requirements, enabling junior staff to produce publication-quality data quickly.

Commercial Impact in Materials Science

The Apreo 2 addresses key pain points in advanced materials characterization labs worldwide.

Demand grows as industries push for nanoscale insights in electric vehicles, renewables, and microelectronics.

Its ease-of-use lowers barriers, expanding the user base and potential revenue streams for Thermo Fisher.

On-demand webinars highlight its role in saving time while enhancing data quality across modalities.

Competitive edge lies in combining UHR-SEM performance with analytical power at extended distances.

Integration with Broader Thermo Fisher Ecosystem

Thermo Fisher positions Apreo 2 alongside tools like EVOS M5000 imaging systems and Celleste software for comprehensive workflows.

While focused on electron microscopy, it complements light microscopy setups for hybrid imaging approaches.

Labs upgrading from older SEMs find seamless integration, with options for expanded analytics.

This ecosystem strengthens Thermo Fisher's dominance in life sciences and materials analysis markets.
