Ultra-High Resolution SEM for Confident, Multimodal Imaging
Tescan CLARA™ is designed for researchers who need fast and reliable nanoscale imaging without compromising sample integrity. With BrightBeam™ field-free optics and In-Flight™ automation, CLARA™ delivers high-resolution, contrast-rich data across materials, battery, and life science applications. It simplifies complex imaging tasks and adapts to your workflow, so you can focus on results.
High Resolution at Low Voltage
BrightBeam™ optics deliver field-free surface-sensitive imaging even below 1 keV, making them ideal for use with beam-sensitive, non-conductive, or magnetic samples.
Rich Contrast Selection
CLARA™'s in-column Multidetector and Axial detector capture topographic and material contrasts in a single scan. Energy-filtered BSE isolates surface-level material contrast, enhancing visibility of composition. Angular BSE filtering reveals contrast differences based on take-off angle. This multimodal setup provides deeper insight into complex or layered materials.
Automation That Works for You
In-Flight™ Automated controls handle beam centering, focusing, and contrast optimization, reducing the number of manual steps required and improving consistency across sessions.
Correlative Imaging, Simplified
Combine SEM with Raman (Tescan RISE) or Serial Block Face Imaging (SBFI) for integrated spectral and structural analysis without transferring your sample.
Built for Flexibility
CLARA™'s adaptable, user-friendly software GUI makes it easy for everyone to operate. Options like no-code workflow building, open scripting with full control, and a flexible, large analytical chamber make it a solution that can be adapted to emerging needs. It's an ideal solution for both industrial R&D and research laboratories.
Designed for routine life‑science imaging and 3D analysis, helping you move efficiently from overview to ultrastructure without compromising data quality.
Ultra-high-resolution imaging: From large-area overviews to nanoscale detail for fast, confident sample analysis
Gentle imaging conditions: Low-keV operation preserves delicate biological structures while minimizing beam damage
