Telescope accessories Capacity Quantum efficiency at 500 nm (green range)

Quantum efficiency describes what percentage of the photons that fall on a chip generate energy in the form of electrons. In concrete terms, this means how effective a chip is, for example, in comparison to a chemical film. Incidentally, these had a quantum efficiency of about 5%. So a modern CCD chip can gain more information in a shorter period of time.
