Folded Infrared Continuous Zoom Lenses for Airborne EO Systems
Optimize payload gimbal systems with folded optics design
The use of folded optics enables the creation of ultra-compact electro-optical systems, mainly gimbals, with unparalleled image quality. This technology paves the path to incorporating a large aperture lens with long effective focal length (EFL) and extended vision ranges (DRI’s), while minimizing the total size of the payload gimbal.
Enhancing gimbal volume usage
Folded optics designs better utilize the available volume for both lens and detector modules. This reduction in size is accomplished by “doublefolding” the lens optical axis back on itself by two, reflecting mirrors at 45° AOI, significantly reducing the overall length of IR lens.
Ophir FoldIR lenses: tailor made for payload gimbal systems
The new FoldIR product family of zoom lenses, developed by MKS Ophir, utilizes a double-folded design to generate small-size, lightweight, small aperture and long vision (DRI) ranges. These continuous zoom lenses enable near diffractionlimit performance in harsh environments, addressing challenges such as line-of sight (LOS) stabilization and athermalization. This makes them ideal for advanced UAS IR cameras, creating crisp, clear images in a wide range of conditions.
- Meets low-SWaP demand with long-range observation capabilities.
- Efficient folded optics design for maximum volume use.
- Designed for variable size thermal imaging aerial gimbals and various other volume constrained platforms.
- Focus is maintained through the entire zoom range, providing extremely fast zoom and focus response.
