LightIR 10-135 mm f/3.6 Motorized MWIR Zoom Imaging Lens
LightIR 10-135 mm f/3.6 Motorized MWIR Zoom Imaging Lens
The Smallest and Lightest Continuous Zoom Lens Designed for MWIR 10μm VGA Detectors
The Ophir LightIR 10-135mm MWIR f/3.6 continuous zoom lens is a compact thermal imaging lens, optimized for 10μm pitch VGA FPA (focal plane array) detectors. It weighs only 250gr, which makes it 20% lighter than existing similar lenses. Its compact optic design significantly decreases the length and weight of the lens, and therefore, the overall size and weight of the optical system in which it is incorporated.
With its unparalleled combination of low-SWaP capabilities, detection range exceeding 11km, and a specialty coating to withstand harsh, humid and salty environments, the LightIR 10-135mm f/3.6 continuous zoom lens is an enabler for advanced drone, tactical UAV IR cameras, and micro/mini tactical payloads in the commercial, homeland security, and defense markets.
Key features:
- 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

LightIR 10-135mm 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)
