Flexible Detection for Clear Images

  • Tailor Sigma to your needs using the latest detection technology and characterize all of your samples.
  • Acquire topographical and compositional information with the optional InLens Duo detector.
  • Enjoy a new generation of secondary electron (SE) detectors. Obtain images with up to 50% more signal. Benefit from the novel C2D and VPSE detectors of Sigma in variable pressure mode: working at low vacuum, you can expect crisp images with up to 85% more contrast.
Save time with Sigma’s 4-step workflow.

Automate and Speed up Your Workflow

  • A 4-step workflow lets you control all the functionality of your Sigma. Benefit from fast time-to-image and save time on training - especially in a multi-user environment.
  • First, navigate your sample and then set optimal imaging conditions.
  • Next, automatically acquire images across multiple samples utilizing regions of interest (ROIs). Finally use the workflow’s last step for contextual visualization of your results.
Speed up X-ray analyses with best-in-class EDS geometry.

Perform Advanced Analytical Microscopy

  • Combine scanning electron microscopy and elemental analytics: the best-in-class EDS geometry of Sigma increases your analytical productivity, especially on beam sensitive samples.
  • Get analytical data at half the probe current and twice the speed. 
  • Achieve complete, shadow-free analytics in your FE-SEM. Profit from using a short analytical working distance of 8.5 mm and a take-off angle of 35°.

Gemini Optics

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.
