WebFigure 1 shows the full photon transfer curve and the apparent change in the measured conversion gain with signal level for a VIRGO-2K detector, SCA-module#31. Th e apparent change in the conversion gain as measured by the photon transfer technique is typically up to 15% for signal levels ranging from 20 to 70% full well capacity. WebThe photon transfer curve is one of the most valuable tools for calibrating, characterizing, and optimizing the performance of CCDs and CMOS Imagers. Its primary purpose is to determine the conversion gain of the system from camera which many of the other performance parameters such as read noise, dark current, QE, full well etc. are determined.
