Features

  • Static or Dynamic Focus: The ability to maintain focus on a variety of surfaces and substrates that are stationary or moving in real-time.
  • Flexibility: Supports integration with WDI Z-axis actuators and can interface with many different third-party Z motion systems including; Piezo actuators, and Dover Motion’s DOF-5.
  • Offset Adjuster (OA) lens versions available to compensate for variances between the sensor focal plane and the camera imaging plane.
  • Available laser wavelengths include 658nm, 785nm, 850nm.

Applications

  • Precision microscopy in biomedical and semiconductor industries, including glass inspection, live cell imaging, high content screening, genotyping and DNA sequencing applications.
