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.
  • Finally, SmartSEM Touch collects and presents your data as an interactive map so you can understand your sample completely.

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 Inlens 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.

Software

SmartSEM Touch

ZEISS SmartSEM Touch - Get more Hands on Deck

SmartSEM Touch, an add-on to the established operation system, is a simplified user-interface for multi-user environments. It comes with easy operation for both experienced and novice users. Depending on the actual laboratory environment, operation of the SEM can be the exclusive domain of expert electron microscopists. But this situation is challenged by the very common necessity that non-expert users, such as students, trainees, or quality engineers, also require data from the SEM. Sigma 300 and Sigma 300 VP take both requirements into account, with user interface options that cater to the operational needs of experienced microscopists as well as non-microscopists.
