New High Resolution Low Light Andor CB2 sCMOS

Oxford Instruments, leading provider of high technology products and services for research and industry, has today announced the launch of a high resolution, low noise, back-illuminated sCMOS camera, further strengthening its broad portfolio of cameras for low light imaging in Life Sciences, Physical Sciences and Astronomy applications.

The CB2 24B features a back-illuminated 24.5 Megapixel sCMOS sensor that combines high sensitivity with high speeds and global shutter. It enables high-resolution imaging over a wide field of view, capturing exceptional detail without compromise.

A remarkably flexible and adaptable camera, it can be applied across a broad range of imaging speeds and exposure conditions, from imaging of fast-moving objects or photometric variability at hundreds of frames per second (fps), to imaging of extremely low light signal with exposures up to several minutes, due to its ultra-low dark current down to 0.0015 e-/pix/sec with -20°C TEC cooling. Consequently, Andor CB2 24B finally offers a true alternative to deep-cooled CCD cameras for long exposure applications such as bioluminescence or astro-photometry/astro-spectroscopy.

Furthermore, the unique ‘on-chip’ 2x2 pixel binning feature allows the native 2.74μm pixel to be converted to a 5.48μm pixel without increasing the read noise. This inherent optical flexibility significantly expands the application adaptability of the camera. For example, in microscopy, the effective pixel size can be set to match objectives from 10x through to 60x.

The global shutter ‘snapshot’ exposure capability, as well as assuring temporal correlation across all pixels and avoiding spatial distortion when imaging fast-moving objects, also renders the camera suited to applications such as particle imaging velocimetry for fluid dynamics, where a short inter-frame gap is essential. The lack of a mechanical shutter also presents a low maintenance solution to remote astronomy and X-Ray tomography. Additionally, Andor CB2 24B has been low-temperature qualified for operation down to -40°C ambient, perfect for observing in high altitude or harsh environments.
