The two lens zoom system is adjusted by the heat-resistant knobs under the front of the unit between 17° and 36°. The closer the two lenses are to one another, the wider the beam angle - the further apart, the narrower. This wide range of beam angles and extremely sharp definition of the beam edge and gobos is achieved by using an extra, high quality, bi-convex condensing lens behind the gate. This, coupled with the polished reflector, gives this unit its unique quality. In all other respects it is similar to the Z0602 reflector zoom profile.
To give a "peaked" or "flat" beam, the lamp position is adjustable. The heat-resistant rear handle and the "T" shaped tilt locking handle give easy, cool control when adjusting the unit's position.
