The Hitachi S-3400N is a high-performance, variable pressure Scanning Electron Microscope (SEM) designed for advanced imaging and analysis.
Featuring guaranteed high resolution of 3.0nm (SED image in high vacuum mode at 30kV) and 4.0nm (BSED image in VP mode at 30kV), this SEM supports magnification from 5X to 300,000X. The large chamber accommodates specimens up to 200mm in diameter, with motorized 5-axis eucentric stage for precise sample positioning.
Key features include:
High Resolution SEM: 3.0nm in high vacuum, 4.0nm in variable pressure mode
Variable Pressure Operation: 6Pa to 270Pa selectable range
Advanced Detectors: Everhart-Thornley SE detector, super-thin five-segment BSE detector (compositional, topographic, 3D modes), optional environmental SE detector
Automatic Functions: Auto brightness/contrast, focus, stigmator, filament saturation, beam alignment, objective aperture alignment
Image Processing: Pseudo color, digital zoom, contrast/brightness adjustment, local contrast, cropping, resizing, gamma control, edge enhancement
Data Management: SEM Data File Manager, PCI Image Management System, full annotation, measurement, stereo pair generation, image optimization
User-Friendly Operation: Windows-based control, 19” LCD monitor, full knob-set and keyboard, stage memory, image navigator, 3D maintenance videos
Safety & Reliability: Rapid start, anti-vibration system, safety interlocks, complete spare parts kit, installation and training included
Ideal for research, materials science, and industrial applications requiring high-resolution SEM imaging and flexible sample handling.
