The LightIR 10-135mm and 18-225mm f/3.6 continuous zoom lenses, are lightweight, compact, thermal imaging lenses, optimized for VGA 10µm detectors. The lenses feature a compact design with reduced optical elements that 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.
The LightIR 10-135mm f/3.6 lens weighs only 250gr, making it 20% smaller than similar lenses and the smallest continuous zoom lens on the market today. The LightIR 18-225mm f/3.6 lens weighs only 300gr, making it also significantly smaller than similar lenses.
Along with a detection range exceeding 11km (by 10-135mm lens) and 15km (by 18-225mm lens), these new LightIR lenses are ideal for the demanding requirements of SWaP and small gimbal thermal imaging applications, such as drones and tactical UAV's in the commercial, homeland security, and defense markets.
With NFOV of 2.7° (10-135mm lens) and 1.6° (18-225mm lens), the innovative design of the lenses enables near diffraction-limit performance in harsh environments. This design also addresses such challenges as line-of-sight (LOS) stabilization, athermalization, maintaining focus throughout the entire zoom range, and high imaging performance. The mechanical and electrical interface of the lens assures easy integration into camera systems.
