Ultra-small SWIR camera for extreme day and night vision operations

Identification of threats and danger at all times and long distance now made possible

Evolving threats around the world and the imminent danger of public safety calls for state-of-the-art products designed to perform new functions. The Rufus-640 camera tackles the challenge to operate during day and night and in varying conditions.

Rufus-640 detects short wave infrared (SWIR) radiation between 0.9 and 1.7 μm with a wide dynamic range and wide operating temperature. The Thermo Electric (TE) stabilization reduces the dark current and noise levels. Together with on-board image processing, such as auto exposure and auto gain, Rufus-640 reaches best contrast and high image quality.

These advanced features result in superior situational awareness despite fog, haze or high humidity and during bright daylight or moonless nights utilizing the night glow. The SWIR camera is also very well suited for camouflage detection, long range identification, detection of specific lasers or other markers unlike other technologies.

Xenics’ Rufus-640 is extremely compact and versatile for easy integration in any configuration. The camera can be easily combined with our thermal cameras “Raven”, boosting detection, recognition and identification to unseen levels.
