Micro-SWIRtm 640CSX Camera
Mil-Rugged, High Sensitivity, Small SWaP,+C InGaAs SWIR Camera
The compact 640CSX is the next generation SWIR video camera,
designed for applications requiring small Size, Weight, and Power
(SWaP) applications and available without ITAR restriction.
The Sensors Unlimited Micro-SWIR 640CSX camera features a
640x512 pixel, high-sensitivity, stabilized InGaAs snapshot imager and
utilizes Sensors Unlimited’s advanced image enhancement algorithms
to produce highest quality imagery in all lighting conditions.
The camera provides real-time daylight to low-light imaging in the
Short Wave Infrared (SWIR) wavelength spectrum for a range of
applications that include industrial process monitoring, enhanced
vision, and persistent surveillance. On-board Automatic Gain Control
(AGC) optimizes the camera's dynamic response throughout day and
night imaging scenarios. Camera Link® digital output provides for
plug-and-play video with 12-bit images for digital image output.
The light weight, compact size, and low power draw are ideally suited for
integration into commercial systems and industrial process monitoring
applications. Optional NIR/SWIR technology is available to extend the
sensitivity of the 640CSX below 0.9 μm, offering the advantage of both
Near Infrared (NIR) and Short Wave Infrared wavelength response.
