The Andor CB2 is a high-performance scientific imaging platform that delivers a powerful combination of exceptional sensitivity, fast frame rates, and a global shutter, all while capturing a wide field of view. With its ultra-low dark current, the CB2 is exceptionally well-suited for low-light and long-exposure imaging applications.
The CB2 24B model is equipped with a 24.5 Megapixel back-illuminated sensor, offering high sensitivity and detailed resolution across a large imaging area. Unique to this model is its ‘on-chip’ 2×2 pixel binning capability, which enables transformation of the native 2.74 µm pixel to 5.48 µm without increasing read noise—providing greater optical flexibility and enhancing the system’s versatility across applications.
The CB2 24B shines in long-exposure applications like luminescence imaging and astronomy, which traditionally challenge sCMOS technology. For exposures lasting several seconds to minutes, dark current becomes the dominant noise factor. This camera addresses that with thermoelectric (TE) cooling down to -20°C, reducing dark current to just 0.0015 e⁻/pixel/second—a figure 100 to 1000 times lower than typical sCMOS cameras. As a result, the CB2 24B stands out as a strong alternative to deep-cooled CCD cameras for many low-light use cases.
Moreover, the CB2 is qualified for use in environments as cold as -40°C, making it ideal for deployment in high-altitude or extreme field conditions.
When it comes to speed, the CB2 24B doesn’t disappoint—delivering up to 74 frames per second (fps) at full 12-bit resolution, and up to 283 fps when using 2×2 binning. This performance makes it excellent for observing dynamic processes across multiple timescales, including ion flux imaging, cell motility studies, adaptive optics, speckle interferometry, and quantum dynamics involving ions or neutral atoms.
For reliable data transfer, the CB2 supports both CoaXPress 2.0 and GigE interfaces, enabling low-latency and stable transmission even across long cable runs. The camera comes with a standard C-mount for broad compatibility, while a TFL mount is also available for use with longer focal length optics.
