The FoldIR 50-1350mm f/5.5 continuous zoom lens is based on a unique folded-optic design with the longest focal length of 1350mm and a 27x motorized zoom ratio, suited for VGA and HD IR sensors. The lens is optimized for stabilized payloads with capabilities for highresolution vision and identification in harsh environmental conditions and on constrained platforms while maintaining focus and tight line of sight (LOS) retention through the entire zoom range. Such features open up new commercial and defense applications, such as visualizing objects and situations that may not be visible to the human eye, for small size UAVs, threats at airports and state borders, gas leaks, and more.

SupIR 50-1350mm f/5.5 f/4.0 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)
