Lightweight Zoom Lenses for Thermal Imaging EO Systems

The outstanding optomechanical design of the MWIR and LWIR LightIR product family ensures that these lenses are the lightest and most compact on the market today, while still achieving the highest levels of imaging performance.

• High MTF performance
• Lightweight, compact configurations
• Optimized for stabilized payloads
• Suitable for a wide range of reduced SWaP applications
• Maintain focus through the entire zoom range
• Cost-effective design and structure

The LightIR 10-135mm and 18-225mm f/3.6 MWIR cooled continuous zoom lenses, are lightweight, compact, thermal imaging lenses, optimized for VGA 10µm detectors. The lenses feature a compact design with reduced optical elements design that significantly decreases the length and weight of the lens resulting in a more compact and lightweight optical system.

• LightIR 10-135mm f/3.6: Weighs only 250gr, making it 20% smaller than similar lenses and the smallest continuous zoom lens on the market today.
• LightIR 18-225mm f/3.6: Weighs only 300gr, significantly smaller than similar lenses.

With detection range exceeding 11km and 15km respectively, these new LightIR lenses are ideal for the demanding requirements of SWaP and small gimbal thermal imaging applications.

The LightIR 16-180mm f/3.6 is a compact, thermal MWIR cooled imaging lens optimized for 10µm pitch VGA FPA detectors. Featuring a folded optics design that significantly reduces the length of the lens and, therefore, the overall size and weight of the optical system in which it is incorporated. The lens is 65% smaller than existing MWIR 10µm VGA lenses. This makes it ideal for the demanding requirements of reduced size, weight, and power (SWaP) and small gimbal thermal imaging applications.
