Ophir Optronics has released the LightIR f/3.6 family of high-performance continuous zoom lenses, optimized for MWIR 640×512 VGA 10µm detectors and ideal for low-SWaP thermal imaging applications such as tactical UAV (unmanned aerial vehicle) gimbals and payloads.

LightIR f3.6 MWIR continuous zoom lensThe new series of lightweight and compact lenses includes three models, with focal length ranges of 10-135 mm, 16-180 mm and 18-225 mm. The 16-180 mm lens features a folded optics design that significantly shrinks the integrated optical system. This design allows extended optical lengths, resulting in reduced sensitivity to tolerances in compact configurations.

All lenses feature high MTF performance and maintain focus through the entire zoom range, and can be easily integrated into a wide range of camera systems. They are equipped with Ophir’s state-of-the-art zoom controller, which 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

A comprehensive communication protocol controls full functionality of the lenses and provides full status reports, 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.

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
