A twin axis, double mirror system is orthogonal so the beam field always remains symmetrical. Other mirror devices can't maintain symmetry, making them entirely unsuitable for theatre use other than as special effects.

Unlike driven yoke systems, the WWG head delivers 360° of tilt and 360° of pan and thus total orbital positioning without moving the luminaire itself. Beambender is mechanically resilient and inaudible.

Proportional control of the stepper or servo motor drives is by DMX 512, complete with 16-bit option.

Programming can be by WWG's 'Virtual Light' software which simulates the motion control favoured by automated yoke manufacturers, or by the microstepping algorithms conventionally used by the waggly mirror brigade.

We are always looking for new applications and development partners to widen the market for their technology. Among existing licensees the two best known are Coemar, with their NAT and XT TM products, and Xenotech Strong, licensees in the USA for RazorHead, a giant version of the device. Used in combination with their 4,7, and 10 kW searchlights, Dick Hart, President of Xenotech Strong, describes the head and xenon combination variously as: "A smart head on strong shoulders" and "A partnership made for the heavens".

In November 1999, WWG added Robert Juliat to this select group with an agreement for this globally respected maker of theatre luminaires, to use the orbital head on their automated 2.5kW HMI luminaire called Fantôme.
