Illumination
The key to excellent color reproduction is the illumination system. For a light sour-
ce the ARRISCAN uses an array of LEDs, which are characterized by low power
consumption, high efciency, excellent color separation and great durability. LEDs
guarantee perfect image quality and place the lowest possible strain on the lm by
minimizing thermal dissipation.
The illumination is digitally adjusted and optimized to suit different lm stocks
via a closed loop regulation system. In addition LEDs will not change their spectral
characteristics; there is no drift and no ageing.
A database keeps track of the illumination parameters used with a given lm
stock and the results achieved by an ARRISCAN will be repeatable over time with
different machines
