C-RED 2 Extended Range: New Perspectives in SWIR Imaging

While standard InGaAs detectors cover a spectral range from 900 to 1700 nm, ER-InGaAs detector sensitivity is shifted towards higher wavelengths up to 2200 nm, and this is a real breakthrough in SWIR imaging. C-RED 2 Extended Range (ER) is a highly sensitive extended short wave infrared camera developed as a versatile platform to integrate ER-InGaAs VGA detectors (640 x 512 pixels). Currently, two versions of the camera are available: the C-RED 2 ER 1.9 µm, integrating an extended range detector sensitive from 1100 to 1900 nm and the C-RED 2 ER 2.2 µm integrating a detector sensitive from 1300 to 2200 nm.

C-RED 2 ER combines high framerates (up to 600 frames per second in full frame) to high sensitivity with a readout noise below 40 e- for C-RED 2 ER 2.2 µm at its nominal temperature of -55°C, and below 50 e- for C-RED 2 ER 1.9 µm at its nominal temperature of -40°C, with liquid cooling. C-RED 2 ER can operate with different readout modes and achieve high-speed frame processing. The camera runs at 600 FPS with embedded corrections: bad pixels correction, 2-point Non-Uniformity Correction, etc… which can be applied with no degradation of the image spatial resolution, loss of speed, or restriction on framerate. By enabling the detection of light at wavelengths beyond the 1700 nm cutoff of standard InGaAs,

C-RED 2 ER opens new perspectives for a wide range of applications from research to high-end industry: hyperspectral imaging for waste sorting, food inspection or pharmaceuticals, thermography, fluorescence imaging, surveillance, laser detection for defense and communication…

C-RED 2 ER is part of the C-RED range of cameras from First Light Imaging: Designed for scientific or industrial applications where sensitivity, speed, dynamic and resolution are essential, the C-RED range of cameras offer advanced solutions for every application and every budget.
