Space Telescope Science Institute   4.2.2 CCD Spectral Response  4.2.4 CCD Long-Wavelength Fringing

4.2.3 Quantum Efficiency Hysteresis


Based on current data, the ACS CCDs do not suffer from quantum efficiency hysteresis (QEH). The CCDs respond in the same way to light levels over their whole dynamic range, irrespective of the previous illumination level.
