Features

SupIR 30-385mm f/5.5 Detection, Recognition & Identification (DRI) Range

DRI ranges enable one to easily estimate the maximum range that an object can be either detected, recognized or identified. It is important to note that these estimates are based solely on geometrical parameters – the target size, distance, lens focal length and camera detector pixel size. Signal level, detector sensitivity, atmospheric conditions and other factors are not considered!

The calculations used here are based on the “Johnson Criteria”. According to the Johnson Criteria, the minimum resolution, pixels on target, required to achieve a 50% probability for an observer to discriminate an object are:

  • Detection: An object is present – 2 pixels on target (Lower Bar)
  • Recognition: discern the type of object, a human vs. a vehicle – 8 pixels on target (Middle Bar)
  • Identification: discern specific objects, a man vs. a woman, a car model – 12.8 pixels on target (Upper Bar)

Your Long Range Distance Needs Met

Long Range, High Performance

Our MWIR f/5.5 lenses enable longer detection, recognition, and identification (DRI) ranges with a compelling combination of performance, reliability and cost, specially designed for anti-drone applications and ideal for long range observation and surveillance systems with vehicle detection range capabilities exceeding 22 km.

Ruggedized Optical Design

These thermal imaging lenses are designed to withstand harsh environmental conditions with ease of mechanical integration. They are ruggedized with Ophir’s standard, world-renowned coatings, IP 67 front sealing, and mechanical design to withstand severe shock and vibration.

Superior Zoom Controller

These lenses are equipped with Ophir’s state-of-the-art zoom controller 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

Optimal Integration and Calibration

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

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

High Performance Mid-Wave Focal Plane

Using advanced technologies, top-quality materials and unique coating techniques, together with innovative engineering and opto-mechanical designs, we have earned a reputation for excellent performance, durability and quality.
