Your Field Emission SEMs for the Highest Demands in Imaging and Analytics from Any Sample
Gemini 1 - What You Always Wanted to Know about the Basics
Field emission SEMs are designed for high resolution imaging. Key to the performance of a field emission SEM is its electron optical column. Gemini is tailored for excellent resolution on any sample, especially at low accelerating voltages, for complete and efficient detection, and ease-of-use.
Gemini optics is characterized by three main components:
- The Gemini objective lens design combines electrostatic and magnetic fields to maximize optical performance while reducing field influences at the sample to a minimum. This enables excellent imaging, even on challenging samples such as magnetic materials.
- Gemini beam booster technology, an integrated beam deceleration, guarantees small probe sizes and high signal-to-noise ratios.
- The Gemini Inlens detection concept ensures efficient signal detection by detecting secondary (SE) and backscattered (BSE) electrons in parallel minimizing time-to-image.
For your applications benefit from:
- Long-term stability of the SEM alignment and the effortless way it adjusts all system parameters such as probe current and acceleration voltage.
- Achieve distortion-free, high resolution imaging with the help of the near magnetic-field free optics.
- Get information solely from the top-most layer of your samples with the Inlens SE detector that produces images out of the truly surface sensitive SE 1 electrons true.
- Obtain true material contrast at very low voltages with the detection concept of the Inlens EsB detector.
