Low-SWaP Excellence with Folded Optics Design

Ophir lenses are engineered to deliver a compact and lightweight solution, significantly reducing the overall size and weight of integrated optical systems—perfect for low-SWaP applications. The 16-180mm and 40-450mm lenses feature an innovative folded optics design, enabling extended optical paths in a drastically reduced form factor. Such design makes them ideal for space-constrained applications such as drones, unmanned aerial systems (UAS) and gimbal-mounted electro-optical systems.

Where Minimal is Critical

The LightIR f/3.6 lenses are ideal for low-SWaP and small gimbal thermal imaging for drones and tactical UAVs in commercial, homeland security, and defense markets.

Superior Zoom Controller Features

These lenses are equipped with Ophir's state-of-the-art zoom controller that features:

  • Continuous zoom with focus retention
  • Automatic focus compensation throughout temperature and zoom ranges
  • Close objects focus mode
  • Focus blurring for NUC calculation
  • Full manual / automatic control of zoom and focus positions

 

Full functionality communication protocol

The communication protocol controls full functionality of lens and full status report of lens, including motor positions, FOV, temperature, built in test status and working hours. Both the controller and communication protocols are fully compatible with all Ophir zoom lenses.

Optimal integration and calibration

For optimal integration and calibration, the lenses are operated with Ophir's standard OphirSim™ software which includes:

  • Lens operation testing and evaluation
  • Protocol simulation
  • Lens customer calibration
  • Autofocus calibration
