NAVAL

Clearview in harshest vision conditions

Ophir’s naval thermal imaging lenses give you the power to see clearly through total darkness and solar glare, as well as light fog and smoke. Our lenses can be used for multiple defense missions, such as navigation, collision avoidance, threat detection, surveillance, and search and rescue missions. The lenses are designed to meet the extreme environmental conditions often experienced at sea, including high humidity, vibrations, saltwater and salt fog.

Ophir’s continuous zoom lenses are available for various FPA formats, including High Definition XGA and SXGA, providing a crisp clean image over full zoom range, MTF close to the diffraction limit and outstanding detection, recognition and identification (DRI) ranges.


With decades of knowledge and experience, having delivered thousands of continuous zoom lenses for defense and naval applications, Ophir has earned its reputation as a world leading one-stop-shop for IR continuous zoom lenses. Our R&D engineering team works in collaboration with our defense customers and leading detector manufacturers, to develop and design optimized optics with unparalleled optical performance quality – for which we are known worldwide.
