The Starbeam is a custom built 4w RGB (white light) fixed beam laser. It is controlled fully by 8 channels of DMX.
As well as the colour changing single beam function, it also has a selectable rotating starburst diffraction grating. DMX control allows the speed and direction of the burst grating to be controlled by a lighting desk. The rotating diffraction effect is designed to be an eye safe effect, and is used on shows where audience exposure effects are required.
