Issue:
CCD imaging sensor well depth capacity.
Solution:
Full well capacity, often described in terms of electrons, defines the amount of charge an individual pixel can hold before saturating. Saturation must be avoided in high-performance CCD imaging because it diminishes the quantitative ability of the CCD and produces image smearing due to a phenomenon known as blooming. Well depth is dependent upon a variety of factors, including the pixel size of the CCD and the operating voltages used on the CCD.
