GEN2 to GEN3 Controller Upgrade
GEN2 to GEN3 Controller Upgrade
fiber optics Introduction
Ophir is upgrading all its zoom lenses from Gen2 to a new Gen3 controller.

The Gen 3 controller has been developed to meet new demands, now & into the future. It has the same dimensions as Gen 2 & is usable with all Ophir zoom lenses.
Benefits
  • Single controller for all zoom lenses, means single customer interface to all Ophir zoom lenses.
  • Single PC simulator application for all Gen3 zoom lenses, enabling calibration & testing of any Ophir lens using single program.
  • Same Form Fit Function (FFF) as Gen2, for seamless, effortless replacement.
  • Improved performance.
  • New features, including:
    • Motor current and position monitoring
    • Autofocusing
    • Larger processing unit, enabling addition of new features upon request
