LightIR 16-180mm f/3.6 Folded-Optic Zoom Lens
The Ophir LightIR 16-180mm MWIR f/3.6 continuous zoom lens is a compact thermal imaging lens optimized for 10μm pitch VGA FPA (focal plane array) detectors.
It features 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 (medium wave infrared) 10μm VGA lenses. With its disruptive combination of SWaP capabilities, detection range over 13+ km, and cost-effective pricing, the new zoom lens is an enabler for advanced drone, tactical UAV IR cameras, as well as micro-/mini-tactical payloads in the commercial, homeland security, and defense markets.
With a focal length of 16-180mm and an f/stop of 3.6, the latest LightIR is a compact, high performance, motorized continuous zoom lens. 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.
