FoldIR 16-180mm f/3.6 10µm VGA MWIR Zoom Lens
FoldIR 16-180mm f/3.6 10µm VGA MWIR Zoom Lens
The FoldIR 16-180mm f/3.6 is a lightweight, compact, thermal imaging lens optimized for smaller size 10 µm pitch 640x512 FPA detectors. It features a unique folded optics design that significantly reduces the integrated optical system in which it is incorporated. The lens is 65% smaller than existing MWIR 10 µm 640x512 lenses.
- Meets low SWaP demand with long EFL
- Efficient folded optics design for max. volume use
- Designed for MWIR 10 μm pitch 640x512 sensors
- Ideal for mini/ micro tactical payloads
- Detection range exceeds 13 km for vehicle (2.3x2.3 m) 查看所有功能

功能
LightIR 16-180mm f/3.6 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)
