ZEISS SIGMA Based on Proven Gemini Technology
• 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.
• The Gemini in-lens detection concept ensures efficient signal detection by detecting secondary (SE) and/or backscattered (BSE) electrons minimizing time-to-image.
• Gemini beam booster technology guarantees small probe sizes and high signal-to-noise ratios.
