Specially designed for short exposure time applications, C-RED 3 is a very compact high-speed VGA uncooled camera for short wave infrared (SWIR) imaging.
C-RED 3 uses a 640 x 512 InGaAs PIN Photodiode detector with 15 μm pixel pitch for high resolution, which embeds an electronic shutter with integration pulses shorter than 5 μs. The cooling system has been removed and electronics squeezed to give a low size, weight and power consumption camera. C-RED 3 offers high performances at short integration times (below 10 ms).
A patented adaptive bias allows to use the camera in any variable temperature environment. Autonomous, ultra compact and also available for OEM, C-RED 3 offers a solution for every application and every budget.
Easy integration - The camera can be easily integrated in a system thanks to the holes on the bottom, the side, or the front, and has a C-Mount/CS-Mount/T-Mount optical interface for the objective. The core version (without housing) is even more easy to fit any custom system.
High sensitivity - C-RED 3 compensates the dark current, necessarily high for a non-regulated camera, by a very high frame rate. When used in windowing (ROI) mode at higher frame rates (up to 32 066 fps), the dark current is completely negligible.
Real-time adaptive bias/dark correction - To compensate the effects of temperature and exposure time variations on the dark frame, C-RED 3 offers an adaptive correction. Dark frames are automatically computed by the camera firmware. Calibrated in factory, this process eliminates the need to perform multiple experimental bias/dark acquisitions, hence simplifying your experiments.
Electronic shutter - C-RED 3 embeds an electronic shutter with integration pulses shorter than 5 μs in full frame mode.
Windowing and Region of Interest (ROI) - Windowing mode allows to achieve faster image rate while maintaining a very low noise, which is very interesting for FSO applications where a limited number of modes will be corrected, so a smaller amount of pixels are needed.
High frame rate - C-RED 3 can work at 600 fps in full frame mode. The frame rate increases up to several kHz in ROI mode (for example 9.5 kHz for a 64-by-64 pixels ROI).
Low camera latency - The delay between the end of integration and the first valid data on CameraLink in normal readout mode full frame is 22.2 μs (default) and can be tuned down to 7.4 μs.
Numerous synchronization mechanisms - Internal and external triggers allow optimal interface of the camera to the rest of the FSO and AO system (laser, computer, etc.).
