Lightweight Zoom Lenses

SWaP optimized MWIR & LWIR Solutions

Where minimal is critical
The LightIR thermal imaging zoom lenses are the industry’s first  lightweight and high-performance continuous zoom lens, designed for use in a wide range of reduced SWaP applications, including unmanned aerial systems (UAS), unmanned aerial vehicles (UAV), aircraft vision systems, drones, and handheld applications such as thermal imagers (HHTI).

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.

NEW LightIR 18-225mm f/4 MWIR
Introducing the newest addition to the successful LightIR family of low-SWaP, lightweight, long-range, motorized continuous zoom lenses. The LightIR 18-225mm f/4 is a compact, thermal imaging lens suitable for smaller size 10µm pitch SXGA/ HD and 15µm pitch VGA FPA detectors. The lens weight only 326gr, which makes it 19% smaller than existing similar lenses.

It features a compact optic design, with reduced optical elements that significantly decrease the length and weight of the lens, and therefore, the system in which it is incorporated.

With its disruptive combination of SWaP capabilities, detection range exceeding 16km, rugged design, and cost-effective pricing, the LightIR 18-225mm f/4 continuous zoom lens is an enabler for advanced drone, tactical UAV IR cameras, and micro-/minitactical payloads in the commercial, homeland security, and defense markets.

LightIR16-180mm f/3.6 MWIR
The LightIR 16-180mm f/3.6 is a compact, thermal imaging lens optimized for smaller size 10µm pitch VGA FPA detectors. It features a folded optic 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, including drones and tactical UAV IR cameras, and micro-/mini-tactical payloads in the commercial, homeland security, and defense industries. With combination of size, weight, range capabilities, and cost, the new zoom lens is an enabler for advanced drone, UAV, and small gimbal thermal imaging applications.

The folded optics design enables long optical lengths, which produce a reduced sensitivity to tolerances in compact configurations that incorporate fewer optical elements. The innovative design also enables near diffraction-limit performance in harsh environments, and addresses such challenges as line-of-sight (LOS) stabilization and athermalization. It is one of the lightest weight, continuous zoom lenses on the market. It maintains sharp focus over the entire zoom range. The mechanical/ electrical interface assures easy integration into camera systems.
