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 efciency, 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
