ONI Nanoimager

Key features

  • Resolution down to 20 nm allows single molecules to be observed and tracked with high sensitivity.
  • Rapid and precise stabilization of the microscope focus, with locking technology to minimize Z-drift.
  • Post-acquisition drift correction with nanometer precision
  • Precise control and measurement of temperature, with heating elements to keep the entire microscope unit at a stable, uniform temperature.
  • Ideal for live cell imaging, facilitating single-particle tracking.
  • Single molecule localization microscopy in multiple colors and 2 channels. Up to 1W laser power at the source. 8-12 kW/cm² power density at the sample plane.
