180-degree field-of-view fisheye lens

A new lightweight, 180-degree field-of-view (FOV) F/1.4, high definition fisheye lens for use in commercial and defence applications, has been released by Ophir Optics.

The lens is compatible with both HD and VGA format FPAs. Designed to improve the existing 60-, 90- and 120-degree FOV lenses presently used, this lens weighs just 90g and can operate in extreme temperature ranges. 
The external optical surface is coated with a high durability coating or a low reflection hard carbon coating to provide better durability in harsh environmental conditions.
