WebElectron-multiplying CCDs (EMCCDs) are a variant of silicon-based CCDs that use electron multiplication to elevate electron signal greatly above the read noise floor to maximize sensitivity for low-light imaging. WebThis offset value is the same for all pixels. In addition to this uniform offset value, there is another effect that happens on short exposure dark frames. The last pixel read off of the CCD will have a larger value than one that was read off first. This is because reading the pixels off of the CCD takes a certain amount of time.
