Effortless Imaging at Subnanometer Resolution

Image effortlessly in your research, industrial lab or imaging facility with GeminiSEM. It allows sub-nanometer resolution and high detection efficiency, even in variable pressure mode. The new variable pressure mode makes you feel like you’re working in high vacuum.

Notable Features

  • Resolves nm detail even below 50V
  • Increased detection efficiency by up to a factor of 20 in low kV regime
  • Gain the most information on any sample by full in-lens detection in VP mode
  • Inlens EsB detector for energy filtering and detection of low voltage BSE
  • High sensitivity and flexible contrast tuning in STEM and backscattered imaging
