Laser Light Source

Three solid state lasers are used in the ARRILASER, producing monochro- matic light beams in the colors red, green and blue. With a perfect Gaussian shape, very long life expectancy and minimal size as well as power consump- tion, they are the key to the ARRILASER’s unrivalled image quality.

The data for each color channel and pixel is fed to an Acousto-optical Modulator (AOM) as a light intensity value, according to which the beam intensity is controlled. The AOM translates the digital data of each pixel into beam intensity in less than 17 nanoseconds.

Deflection System

Moving parts on the ARRILASER are designed to sustain a minimum of wear. A new aerostatic bearing motor, which encounters no mechanical friction during operation, is used to achieve the speed required for the deflection of the beam. Line by line is written on film in an ultra precision linear stage.

A linear induction motor moves the stage through direct magnetic induction without any additional moving parts such as gears.
