At -80°C, the dark current is negligible but becomes a dominant factor as the 15-minute mark approaches if cooling stability fluctuates.
This paper explores the performance and thermal stability of the Electron Multiplying CCD (EMCCD) during extended 15-minute acquisition cycles. We evaluate the impact of clock-induced charge (CIC) and dark current on image clarity in ultra-low-light environments, specifically for applications in bioluminescence and deep-space observation. 1.

Thermoelectric cooling set to -80°C to minimize dark current. At -80°C, the dark current is negligible but
A integration period is often the "sweet spot" for capturing slow-moving biological processes or faint astronomical nebulae. However, cosmic ray hits increase linearly with time, necessitating robust post-processing algorithms to "clean" the 15-minute frame without losing legitimate signal data. 5. Conclusion However, cosmic ray hits increase linearly with time,
