CCD and CMOS technology are well established, but over the past two decades there has been a shift from CCD towards CMOS devices, in particular for scientific applications tackling low-light and relatively short exposure times. Although CCD technology is still advantageous for applications such as spectroscopy and astronomy, it is limited by relatively higher read noise and slow readout speed. CMOS technology can overcome these limitations, however scaling this to larger formats has hit technology limits, resulting in slower or noisier products. At Teledyne Imaging, we have combined the benefits of CCD-like technology with the advantages of CMOS sensor architecture to create the ultimate CMOS imaging experience. The newly developed LACera™ technology provides deep-cooled, low-noise performance on a large sensor area, with global shutter, high dynamic range, and glow reduction technology all within one sensor. This technology has also been integrated into an astronomy optimized, large format CMOS camera called COSMOS. Combining all of the advantages of LACera™ technology into one fully integrated device, the COSMOS is advantageous for astronomy applications requiring faster frame rates, high sensitivity and low noise, all while offering large sensor areas for multiple object capture per frame.
