Complete Family of Alta Camera QE Curves
Back-illuminated CCDs are typically used for very low light applications due to their high quantum efficiency (QE). Kodak micro-lensed Blue Plus CCDs (ME suffix on the part number) also have high peak QE, but much less overall QE than the back-illuminated CCDs. The UV enhanced versions of the back-illuminated CCDs have the highest QE in the UV. Back-illuminated CCDs have the highest QE in the near-IR, but are subject to etaloning (fringing caused by internal reflections). Interline transfer CCDs can take much shorter exposures and read out at higher frame rates because they do not require electromechanical shutters. Large pixel CCDs have the highest dynamic range, but generally are not suitable for microscopy.
